EU leaders want UK in union, but not treaty change

LONDON: European leaders on Wednesday stressed the importance of keeping Britain in the EU, but said they opposed treaty changes demanded by Prime Minister David Cameron.

"Britain is an essential part of the EU," Irish Prime Minister Enda Kenny said during a conference in Dublin marking the beginning of his country's six-month presidency of the bloc.

"Great Britain has great value and is a very important member of the EU," added EU President Herman Van Rompuy.

The two leaders highlighted the importance of the union for British businesses, saying that it was essential for them that Britain remained a full and active member.

A majority of Britons favour severing all ties with the union, according to polls, and Cameron is expected to deliver a speech within the next few days spelling out his views on the country's relationship with Brussels.

He insisted last year that he supported Britain's membership, but that he wanted to negotiate a "new agreement" which would allow it to opt out of certain directives.

Kenny and Van Rompuy both repeated their opposition to any treaty changes.

"I don't see a reopening of the treaties, I don't see an issue in treaty change for any individual countries," said the Irish prime minister.

Irish Deputy Prime Minister Eamon Gilmore stressed that the top concern of European citizens, "whether from Liverpool or Limerick", was unemployment.

Van Rompuy reiterated that it would be possible to change the treaties after the 2014 European elections, but added that he strongly supported deeper EU integration as opposed to an "a la carte" union.

He pointed out that there was already scope for increasing EU partnership.

"We don't need, at this stage, a treaty change," he said. "We can deliver for a deeper EU within the treaties."

Born of rape, left alone and bereft

BHUBANESWAR/AHMEDABAD: He's just four and is lost and bewildered. Not only is Raghav in a new school in a strange place, he's away from the fond gaze of his doting grandparents. For no fault of his.

In 2007, his mother Meera was raped in Khaprakhol area of Balangir in Orissa. Distraught and depressed, she approached local NGO Kalyan when she was two-months pregnant. "We counselled her and convinced her not to go for an abortion," says Meenakshi Purohit of Kalyan.

But life has been a constant struggle since. Her son was refused admission in school when the teachers discovered that he was born of rape. Later, Meera got him admitted to a school unfamiliar with her status. But for that, she had to leave the security of her parents' home and shift to another place. She's now finding it difficult to earn a living. What's worse, the accused is still absconding.

Meera's story is the story of countless rape victims left to fend for themselves and their children in a cruel and uncaring world. In Orissa alone, there are at least a dozen children in recent times born out of rapes who lead a hand-to-mouth existence in the absence of family or government support.

In Deogarh district, a 14-year-old disabled girl raped by a 70-year-old is jeered by everyone. After she gave birth in July, she's been living with her parents. But her father, a daily wage labourer, can't support her. "She has visited several government offices for help but no one cares," says a local.

There are also cases of parents deserting their raped daughters. A minor who was raped in Balangir is now working in a beauty parlour and fends for her three-year-old daughter after her parents wanted nothing to do with her. Besides the cold indifference of families, there is the insensitivity of authorities.

A Class IV dropout in Kuchinda who conceived after being raped by a neighbour has got little help despite the then state commission for women chairperson Jyoti Panigrahi discussing her rehabilitation with district authorities.

"A rape victim, even if she is not pregnant, is entitled to be rehabilitated under the Criminal Injuries Relief and Rehabilitation Boards scheme. Each victim gets Rs 2 lakh compensation. Collectors should ensure its implementation," says Panigrahi.

But there has been hope and rehabilitation for some. In contrast to these bleak cases, the Patan gang-rape victim in Gujarat has got her life back on the rails. The victim, 23, teaches in a school in rural Gujarat. After a tiring day at work, she heads home to a loving husband who runs a mobile repair shop and a baby boy who makes her run around in circles.

Her amazing comeback story is an example of how rape victims should be treated. After being sexually assaulted by six teachers at Patan Primary Teacher's Training College (PTC) in 2008, she used to hallucinate about monster gurus despite being ensconced in the safety of a home run by an NGO. She would be held, comforted and told that it was all over.

She was lucky. The boy in love with her also proposed marriage. "His proposal in 2010 was something I felt would never happen to me. Even my in-laws treat me like a daughter," she says. Despite post-traumatic stress for months, she passed her studies with distinction and got a government job. She's now at peace. "I wish the outrage over rape allows people to open their hearts and accept rape victims as wives and daughter-in-laws," she says plaintively.

Retooling Pap test to spot more kinds of cancer

WASHINGTON (AP) — For years, doctors have lamented that there's no Pap test for deadly ovarian cancer. Wednesday, scientists reported encouraging signs that one day, there might be.

Researchers are trying to retool the Pap, a test for cervical cancer that millions of women get, so that it could spot early signs of other gynecologic cancers, too.

How? It turns out that cells can flake off of tumors in the ovaries or the lining of the uterus, and float down to rest in the cervix, where Pap tests are performed. These cells are too rare to recognize under the microscope. But researchers from Johns Hopkins University used some sophisticated DNA testing on the Pap samples to uncover the evidence — gene mutations that show cancer is present.

In a pilot study, they analyzed Pap smears from 46 women who already were diagnosed with either ovarian or endometrial cancer. The new technique found all the endometrial cancers and 41 percent of the ovarian tumors, the team reported Wednesday in the journal Science Translational Medicine.

This is very early-stage research, and women shouldn't expect any change in their routine Paps. It will take years of additional testing to prove if the so-called PapGene technique really could work as a screening tool, used to spot cancer in women who thought they were healthy.

"Now the hard work begins," said Hopkins oncologist Dr. Luis Diaz, whose team is collecting hundreds of additional Pap samples for more study and is exploring ways to enhance the detection of ovarian cancer.

But if it ultimately pans out, "the neat part about this is, the patient won't feel anything different," and the Pap wouldn't be performed differently, Diaz added. The extra work would come in a lab.

The gene-based technique marks a new approach toward cancer screening, and specialists are watching closely.

"This is very encouraging, and it shows great potential," said American Cancer Society genetics expert Michael Melner.

"We are a long way from being able to see any impact on our patients," cautioned Dr. Shannon Westin of the University of Texas MD Anderson Cancer Center. She reviewed the research in an accompanying editorial, and said the ovarian cancer detection would need improvement if the test is to work.

But she noted that ovarian cancer has poor survival rates because it's rarely caught early. "If this screening test could identify ovarian cancer at an early stage, there would be a profound impact on patient outcomes and mortality," Westin said.

More than 22,000 U.S. women are diagnosed with ovarian cancer each year, and more than 15,000 die. Symptoms such as pain and bloating seldom are obvious until the cancer is more advanced, and numerous attempts at screening tests have failed.

Endometrial cancer affects about 47,000 women a year, and kills about 8,000. There is no screening test for it either, but most women are diagnosed early because of postmenopausal bleeding.

The Hopkins research piggybacks on one of the most successful cancer screening tools, the Pap, and a newer technology used along with it. With a standard Pap, a little brush scrapes off cells from the cervix, which are stored in a vial to examine for signs of cervical cancer. Today, many women's Paps undergo an additional DNA-based test to see if they harbor the HPV virus, which can spur cervical cancer.

So the Hopkins team, funded largely by cancer advocacy groups, decided to look for DNA evidence of other gynecologic tumors. It developed a method to rapidly screen the Pap samples for those mutations using standard genetics equipment that Diaz said wouldn't add much to the cost of a Pap-plus-HPV test. He said the technique could detect both early-stage and more advanced tumors. Importantly, tests of Paps from 14 healthy women turned up no false alarms.

The endometrial cancers may have been easier to find because cells from those tumors don't have as far to travel as ovarian cancer cells, Diaz said. Researchers will study whether inserting the Pap brush deeper, testing during different times of the menstrual cycle, or other factors might improve detection of ovarian cancer.

Arias Caught Lying to Cops in Recorded Phone Calls

Jodi Arias blatantly lied to police who asked her about Travis Alexander's death, telling them in recorded phone calls that she kept trying to call and message Alexander the week of his death but never heard back from him.

The phone calls were played as evidence during the fourth day of Arias' trial, in which she is charged with murder and could face the death penalty if convicted of killing Alexander in a "depraved and heinous" way. Arias has admitted to killing her former boyfriend, but claims it was self-defense.

During the phone conversations played in court, Arias can be heard telling Mesa, Ariz., detective Esteban Flores that she last talked to Alexander on Tuesday night, June 3, 2008, around 10 p.m. She had been in Los Angeles, about to leave to go to Utah to visit a new love interest, she said.

After June 3, he stopped calling her back, she said.

Photos of Key Players and Evidence in the Jodi Arias Murder Trial

"On Tuesday night (I talked to him), it was brief though, 10 o'clock maybe. I'd say 10 p.m. or 9 - 9:30. I was calling people because I was bored on the road. He was nice and cordial, but kind of acting like he had hurt feelings," she said.

"I may have called him Wednesday, from the road, and I sent him a couple of text messages, and a couple of pictures," she said, though Alexander didn't pick up and his voice mailbox was full. "That's unusual. He deletes all of his messages. I didn't want to be obsessive about it because we're not together anymore and I didn't like to call too much."

According to court records, Arias, 32, actually went to Alexander's home on in Mesa on Wednesday morning. There, the pair had sex and took graphic photos of one another with Alexander's camera.

Then, Arias is believed to have killed Alexander, 30, in his shower by stabbing him, slashing his throat from ear to ear, and shooting him in the head.

In the phone conversations, Arias told Flores that she considered calling Alexander's friends when he stopped returning her calls on Wednesday, but didn't want to act like "his mother."

Alexander's friends found his body five days later with stab wounds and a bullet wound, lying in blood in his home.

Flores asked Arias if she ever considered buying a gun, she said she was too scared of handguns.

Jodi Arias Trial: Defense Claims Victim Was Sex Deviant Watch Video

"I've looked into handguns. I have a list of things I'm scared of that I'm trying to overcome," she said. "I got that from Travis, you know, to push yourself out of your comfort zone, and do things you're afraid of. But handguns are expensive and not really in my price range right now."

Arias is accused of stealing her grandmother's handgun and using it to shoot Alexander in the head during the attack.
The detective interviewed Arias by phone multiple times in June after Alexander's body was discovered by his friends on June 9.

Arias was indicted on July 9, 2008, and changed her story again before her arraignment, telling a TV news station that she was at Alexander's house when he was killed and witnessed two intruders kill him.

After she was arraigned, Arias told police she killed Alexander, but did it in self-defense. Arias's attorneys have said that Alexander was controlling and abusive toward Arias, and described him as a "sexual deviant."

In earlier testimony in court today, Arias's new love interest, Ryan Burns, testified that Arias showed up to his house on the morning of Thursday, Dec. 5, just 24 hours after she killed Alexander.

There, the pair cuddled, kissed, and watched movies, according to Burns.

Burns, who met Arias at a business conference in spring, 2008, said he exchanged frequent long phone calls and online conversations with Arias before inviting her to come visit him in West Jordan, Utah, in June. Arias lived in California at the time.

She arrived at Burns's home 24 hours after she was expected there, telling him that she got lost, drove the wrong way on a freeway for a few hours, fell asleep for awhile, and then got lost again, Burns testified today.

She never told him that she had confronted Alexander with a knife or gun and ended up killing him just hours before their date.

When she arrived, the pair quickly got physical, he testified.

"We went back to my house. We talked for awhile, and agreed that we were going to watch a movie. At some point we were talking and we kissed. Every time we started kissing it got a little more escalated. Our clothes never came off, but at some point she was kissing my neck, I was kissing hers, but our clothes never came off," he said.

Burns said that both he and Arias stopped kissing at the time, though they again became physically involved later in the evening when Arias climbed on top of Burns and began kissing him. Burns said that they stopped kissing because he did not want her to "regret the visit" because of her Mormon beliefs about sex.

He also told prosecutors upon questioning that Arias was physically strong.

"She's very fit," he said, describing their encounter when she climbed on top of him. "She's very strong. She has close to a six pack (of abs)."

Prosecutors likely asked about the strength of Arias because in testimony Tuesday Maricopa County medical examiner Kevin Horn said Alexander was stabbed so forcefully that the blade chipped his skull and his neck was cut all the way back to the spinal cord.

Burns, who is also a Mormon, said he noticed two bandages on Arias's hand when she arrived at his house, which she told him she got when a glass broke at her place of employment, Margaritaville.

During her visit, the pair also went to a business meeting and went out with Burns' friends where Burns described Arias as acting "shy" and a "little awkward."

"She was fine, she was laughing about simple little things like any other person. I never once felt like anything was wrong during the day. With a crowd she was a little awkward in social areas, but one on one she was very talkative and excitable," he said.

Venezuela's top court endorses Chavez inauguration delay

CARACAS (Reuters) - Venezuela's top court endorsed the postponement of Hugo Chavez's inauguration this week and ruled on Wednesday that the cancer-stricken president and his deputy would continue in their roles, despite a cacophony of opposition complaints.

Critics had argued the 58-year-old's absence from his own swearing-in ceremony on January 10 meant a caretaker president must be appointed. Chavez has not been seen in public nor heard from in almost a month following surgery in Cuba.

"Right now we cannot say when, how or where the president will be sworn in," Supreme Court Chief Judge Luisa Morales told a news conference.

"As president re-elect there is no interruption of performance of duties ... The inauguration can be carried out at a later date before the Supreme Court."

The decision opens the door in theory for Chavez to remain in office for weeks or months more from a Cuban hospital bed - though there is no evidence he is even conscious.

It leaves the South American country in the hands of Vice President Nicolas Maduro, as de facto leader of the government.

The opposition say that is a brazen violation of the constitution, and that Maduro should leave office on Thursday when the current presidential term had been due to expire.

They say National Assembly boss Diosdado Cabello, another powerful Chavez ally, should take over the running of the country while new elections would be organized within 30 days.

Maduro would be the ruling Socialist Party's candidate.

Government leaders insist Chavez, 58, is fulfilling his duties as head of state, even though official medical bulletins say he suffered complications after the surgery, including a severe lung infection, and has had trouble breathing.

His resignation or death would transform politics in the OPEC nation, where he is revered by poor supporters thankful for his social largesse, but denounced by opponents as a dictator.

RALLY PLANNED FOR THURSDAY

Opposition leader Henrique Capriles, who lost a presidential election to Chavez in October, said the Supreme Court had become politicized under the socialist leader's administration.

"The tribunal gave an interpretation (of the constitution) in order to solve a problem that the government has," Capriles told a news conference.

Moody's Investors Service warned on Wednesday that Venezuela's sovereign credit rating, already at junk status, faces short-term risks over any political transition.

Prices of Venezuela's widely traded bonds have soared lately on Chavez's health woes, but dipped this week as investors' expectations of a quick government change apparently faded.

The president has undergone four operations, as well as weeks of chemotherapy and radiation treatment, since being diagnosed with an undisclosed type of cancer in his pelvic area in June 2011.

He looked to have staged a remarkable recovery from the illness last year, winning a new six-year term at a hard-fought election in October. But within weeks of his victory he had to return to Havana for more treatment.

The government has called for a huge rally outside the Miraflores presidential palace in Caracas on Thursday, and allied leaders such as Uruguay's Jose Mujica, Bolivia's Evo Morales and Nicaragua's Daniel Ortega have said they will visit - despite Chavez's absence.

Argentine President Cristina Fernandez, a close friend, has announced plans to visit Chavez in Cuba on Friday.

The unprecedented silence by Chavez, who is well known for his hours-long rambling speeches, has convinced many Venezuelans that his 14 years in power may be coming to an end.

Unlike after his previous operations in Cuba, no photographs have been published of him recuperating, and social media in Venezuela is buzzing with rumors he is on life support.

Cabello, the pugnacious head of the National Assembly, has repeatedly ruled out taking over as caretaker president to order a new presidential election, saying Chavez remains in charge.

"Tomorrow we will all go to the Miraflores palace," he told a televised Socialist Party meeting on Wednesday. "The people will be invested as president. We are all Chavez!"

Arianespace says 2012 sales leapt by 30%

PARIS: The European space launch company Arianespace said Tuesday that its 2012 sales rose 30 per cent and forecast that it would dominate Russian and US rivals this year with a market share of more than 60 per cent.

Arianespace sales soared to more than 1.3 billion euros, and the company said that it already covered 60 per cent of the global market last year, bringing its order book to 4.0 billion euros, or three years' worth of activity.

This year, the company plans 12 launches with three different vehicles, the giant Ariane 5 rocket, the smaller Vega, and the Russian rocket Soyuz, up from 10 in 2012, chief executive Jean-Yves Le Gall told a press conference.

He called 2012 a "remarkable" year, noting that the company had launched seven Ariane 5 rockets to mark its 10th consecutive year without a failure, and had put a total of 75 tonnes of satellites into orbit.

Arianespace could even surpass 12 launches this year if one of its rivals is unable to honour their contracts, Le Gall noted, joking: "When they sign contracts we are the one that launches the satellites."

Competitors include the private US firm SpaceX, which developed its own launch vehicle over a period of 10 years and successfully delivered a payload last year to the International Space Station with its reusable Dragon launch vehicle.

The Russian rocket Proton has had a spotty launch record meanwhile, but its successor Angara is set for its first launch this year.

Elsewhere, the US-Russian company Sea Launch is in financial trouble, while Chinese rockets are not yet serious rivals for Arianespace.

The European group still depends on subsidies from countries that have backed it from the beginning, but Le Gall estimated that it needed a little more than 100 million euros last year, down from 125 million a year before, and 250 million 10 years earlier.

Ariane 5 is to be replaced by an Ariane 6 rocket, pending confirmation of that project next year. Arianespace forecasts that it would then be profitable without public aid.

J&K likely to have fifth Kashmiri CS

SRINAGAR: Chief minister Omar Abdullah is learnt to have given his nod to senior-most Kashmiri IAS officer Iqbal Khanday taking over as the new chief secretary of Jammu & Kashmir following the posting of Madhav Lal as secretary, Union government. If appointed, Khanday, a 1978 batch IAS officer, would become fifth Kashmiri chief secretary of the state.

Lal, who has been secretary at the Centre, is likely to join the government by the end of January. Although two other 1978 batch IAS officers, including Anil Goswami and Pankaj Jain, are also in line, the Omar government has tacitly agreed on having a Kashmiri Muslim Iqbal Khanday as the chief secretary. The reasoning is this might help the ruling party in the run-up to the assembly elections in 2014.

If selected, Khanday will follow in the footsteps Vijay Bakaya, Sheikh Ghulam Rasool, Nasrullah and Noor Mohammad. According to sources, the Centre, too, has approved the name of Khanday for the post. Apparently, the tardy bureaucracy has not gone down well with both the Centre and the state government and Khanday's elevation could speed things up for Omar as he braces for tough elections.

Goswami and Jain are in Central deputation. Although Goswami, who is special secretary, home, is from Jammu, the National Conference government considers Khanday more of a key appointment.

Report: Death rates from cancer still inching down

WASHINGTON (AP) — Death rates from cancer are continuing to inch down, researchers reported Monday.

Now the question is how to hold onto those gains, and do even better, even as the population gets older and fatter, both risks for developing cancer.

"There has been clear progress," said Dr. Otis Brawley of the American Cancer Society, which compiled the annual cancer report with government and cancer advocacy groups.

But bad diets, lack of physical activity and obesity together wield "incredible forces against this decline in mortality," Brawley said. He warned that over the next decade, that trio could surpass tobacco as the leading cause of cancer in the U.S.

Overall, deaths from cancer began slowly dropping in the 1990s, and Monday's report shows the trend holding. Among men, cancer death rates dropped by 1.8 percent a year between 2000 and 2009, and by 1.4 percent a year among women. The drops are thanks mostly to gains against some of the leading types — lung, colorectal, breast and prostate cancers — because of treatment advances and better screening.

The news isn't all good. Deaths still are rising for certain cancer types including liver, pancreatic and, among men, melanoma, the most serious kind of skin cancer.

Preventing cancer is better than treating it, but when it comes to new cases of cancer, the picture is more complicated.

Cancer incidence is dropping slightly among men, by just over half a percent a year, said the report published by the Journal of the National Cancer Institute. Prostate, lung and colorectal cancers all saw declines.

But for women, earlier drops have leveled off, the report found. That may be due in part to breast cancer. There were decreases in new breast cancer cases about a decade ago, as many women quit using hormone therapy after menopause. Since then, overall breast cancer incidence has plateaued, and rates have increased among black women.

Another problem area: Oral and anal cancers caused by HPV, the sexually transmitted human papillomavirus, are on the rise among both genders. HPV is better known for causing cervical cancer, and a protective vaccine is available. Government figures show just 32 percent of teen girls have received all three doses, fewer than in Canada, Britain and Australia. The vaccine was recommended for U.S. boys about a year ago.

Among children, overall cancer death rates are dropping by 1.8 percent a year, but incidence is continuing to increase by just over half a percent a year. Brawley said it's not clear why.

Menu Calorie Counts: How Accurate Are They?

They are supposed to help America's obesity problem: calorie counts boldly displayed on restaurant menus across the country and important information, considering Americans now eat one-third of their meals outside the home.

Two states and nine counties require them today, and by the middle of next year, a federal law is expected to force chain restaurants, convenience stores and vending machines nationwide to post calorie counts.

But how accurate are those numbers that so affect your waistline?

A 2011 study by Tufts University sampling food from 42 restaurants says it depends.

Fast food restaurants were the most accurate because of the uniform recipes and portions, but there were wide variations found in sit-down restaurants.

"We found that 20 percent of the foods we tested had 100 calories or more over what was stated on the menu," Lorien Urban, a postdoctoral associate in the energy metabolism lab at Tufts University and first author of the study, told ABC News. "We would consider that to be a considerable amount."

Urban explained that consuming an extra 100 calories per day can lead to an extra 10 pounds in one year.

Most concerning was that a majority of the errors Urban and her colleagues found were made on the diet side of the menu.

Calorie Check: How Many Servings Are You Eating? Watch Video

"These were the foods that people who are trying to manage their weight would gravitate towards and they may be getting more calories than they expect," she said.

ABC News sent producers in three cities that already require posting menu calories to major chains to do a sampling under the direction of a nationally known lab and found that more than half of the low-cal meals tested had more calories than listed on the menu.

In total 24 food samples from four sit-down restaurants and one McDonald's were collected and the results were surprising.

McDonald's did the best. Its Big Mac Meal (posted: 930) and its Premium Chicken Sandwich (posted: 400) tested 30 calories below the menu posting.

But the sit-down restaurants had results sometimes wildly different than advertised.

In all, only one calorie count was accurate -- a Skinnylicious chicken salad sandwich from the Cheesecake Factory.

Eleven meals had more calories than on the menu and 10 had fewer calories. Some were over by only 40 calories; another was over by as much as 420 calories, again at the Cheesecake Factory: This time an order of the fish and chips dinner.

Urban said that fast food restaurants tended to be more accurate than sit-down because of the formulaic preparation that fast food restaurants use.

"Things are arriving already packaged into the restaurants and it's just a matter of warming it up and serving it to the consumer," she said. "A sit-down restaurant, things are being prepared on [the] spot [and] by chance some extra butter gets into the pan."

That can change the calorie amount.

All the restaurants and their trade association say that most calorie counts are as accurate as possible and tested extensively to make sure.

They conceded that there are variations, mostly due to portion size and individual restaurant preparation, and that the menus warn actual calories may vary.

What can you do? Take control of what is put on top of the entree by asking for everything fattening -- such as cheeses, sauces or dressings -- on the side.

Venezuela postpones inauguration for cancer-stricken Chavez

CARACAS (Reuters) - Venezuela will postpone the inauguration of President Hugo Chavez for a new term due to health problems, the government said on Tuesday, another sign the socialist leader's cancer may be bringing an end to his 14 years in power.

The 58-year-old former soldier who has dominated the South American OPEC nation since 1999 has not been heard from since surgery on December 11 in Cuba - his fourth operation since he was diagnosed with an undisclosed type of cancer in June 2011.

The announcement outraged opposition leaders who insist that Chavez must be sworn in before the National Assembly on January 10 as laid out in the constitution, or temporarily step aside and leave an ally in power.

"The commander president wants us to inform that, based on his medical team's recommendations, the post-operative recovery should extend past January 10," said Vice President Nicolas Maduro, Chavez's chosen successor, in a letter read to the legislature.

"As a result, he will not be able to be present at the National Assembly on that date."

The letter said authorities would seek another date for the inauguration ceremony but did not say when it would take place or give a time frame for Chavez's return from Havana.

Rather than being sworn in by the legislature, he would take his oath at a later date before the Supreme Court, the letter said, as allowed by the constitution.

Government leaders insist Chavez is completely fulfilling his duties as head of state, even though official medical bulletins say he has a severe pulmonary infection and has had trouble breathing.

The government has called for a massive rally outside the presidential palace on Thursday, and allied presidents including Uruguay's Jose Mujica and Bolivia's Evo Morales have confirmed they will visit Venezuela this week despite Chavez's absence.

Argentine President Cristina Fernandez has announced plans to visit Chavez in Havana on Friday.

But the unprecedented silence by the president - famous for regularly speaking for hours in meandering broadcasts - has left many convinced he could be in his last days.

His resignation or death would upend politics in the oil-rich nation, where he enjoys a deity-like status among poor supporters thankful for his social largesse.

His critics call him a fledgling dictator who has squandered billions of dollars from crude sales while dashing the independence of state institutions.

CONSTITUTION DISPUTE

The constitution does not specify what happens if the president does not take office on January 10.

The Supreme Court, which has been expected to provide a constitutional interpretation of the issues of the inauguration date, called a press conference for Wednesday.

Opposition leaders argue that Congress chief and Chavez ally Diosdado Cabello should take over, as mandated by the constitution if the president's absence is formally declared.

Cabello has ruled that out, saying the president continues to be in charge.

If Chavez dies or steps aside, new elections would be called within 30 days. Before leaving for Havana in December, the president instructed his supporters to back Maduro in that vote if he were unable to continue.

During a rambunctious session of Congress, opposition deputies accused Socialist Party leaders of failing to follow Chavez's instructions - a scene that would have been unimaginable before Chavez's prolonged absence.

"President Chavez is the only one among you who has spoken clearly," said opposition leader Julio Borges.

He was drowned out by pro-Chavez deputies clapping and chanting the socialist leader's name and rebuffed by Cabello, who had long been considered a potential successor to Chavez until he was passed over for Maduro.

"It's not my fault you weren't chosen, don't take your frustration out on me," Borges quipped.

Another opposition deputy complained that during the debate a copy of the constitution was thrown across the chamber from the direction of the Socialist Party's deputies.

Chavez's supporters have held near-daily vigils for his recovery, while opposition activists accuse the president's allies of a Cuban-inspired manipulation of the situation.

Maduro has taken over the day-to-day running of the government and looks set to continue in the role past Thursday.

The mustachioed former bus driver lacks Chavez's charisma, but he has sought to imitate the president's style with vituperative attacks on the opposition and televised ribbon-cutting ceremonies.

With the micro-managing Chavez away, major policy decisions in Venezuela, such as a widely expected devaluation of the bolivar currency, appear to be on hold.

Venezuelan bond prices, which had soared in recent weeks on Chavez's health woes, dipped on Monday and Tuesday as investors' expectations of a quick government change apparently dimmed.

"The 'regime change' euphoria seems excessive taking into account the unclear legal transition and perhaps, more importantly, the risk that regime change does not allow for policy change," New York-based Jefferies' managing director Siobhan Morden said in a note on the bonds.
