CARACAS, Venezuela — Venezuelan President Hugo Chavez underwent surgery in Cuba on Tuesday for a recurrence of cancer that has thrown his future into jeopardy and upended politics in the South American OPEC nation.
"My dear friend and colleague, Comandante Hugo Chavez, is going through the toughest times of his life," said Ecuadorean President Rafael Correa, a fellow leftist. "He's being operated on right now. It's a very delicate operation."
Venezuela's 58-year-old socialist leader returned to politically allied Cuba for a fourth operation since mid-2011, after cancer was again discovered in the pelvic area soon after he won re-election in October.
Chavez's ministers have been parading on state TV to pledge loyalty to their boss but have given no details of his condition, which is treated virtually as a state secret. A Venezuelan government source confirmed Tuesday's operation.
Having declared himself "completely cured" twice in the past, the president has acknowledged he may be incapacitated, though he said he still hopes to recover in time to start his new, six-year term on January 10.
Chavez has named vice president and foreign minister Nicolas Maduro as a potential successor to lead his self-styled revolution in the South American nation of 29 million people that has the world's largest oil reserves.
Maduro, 50, a former bus driver and union activist, lacks his boss's charisma and political flair but would represent policy continuity should he formally take over. He has already taken control of day-to-day government operations.
The naming of Maduro has irked some in Venezuela's opposition, who say voters — not Chavez — will decide who follows him if an election is held within 30 days of his leaving office, as mandated by the constitution.
"Venezuela is not a monarchy with a prince as heir," said one opposition leader, Antonio Ledezma.
CHAVEZ "IN GOOD SPIRITS"
Should an election be held, opposition flag bearer Henrique Capriles, who lost to Chavez in the October presidential vote but scored a record 6.5 million votes for the opposition, could have a second crack at power.
In a newspaper interview on Tuesday, Capriles declined to speculate on a possible new presidential bid and repeated his best wishes to Chavez for recovery. But he criticized the secrecy surrounding the president's treatment.
"Venezuelans have the right to know," he said.
Chavez was assumed to be a patient once more at Havana's Cimeq hospital, though no official information on the situation was coming out of the communist-run Caribbean island.
Friends around the region have sent messages of support.
"He changed the history of Venezuela and of a large part of Latin America," said Correa, a central member of the Chavez-led Alba bloc of leftist nations in the region, after visiting him in Havana. "He's in good spirits. You know what Hugo's like, always ready for tough battles with optimism and faith. . . . I'm not going to lie, we're very worried. It's a serious matter."
Chavez's health woes sparked a rally in Venezuela bonds, given many investors' preference for a more business-friendly government in Caracas. And in London, veteran emerging market investor Mark Mobius said any change to a more market-friendly government in Venezuela would encourage him to invest there once more.
"Regime change has probably entered into a countdown phase," New York-based Jefferies' managing director Siobhan Morden said in a research note.
The health saga has once again eclipsed major national issues such as state elections on Sunday, a widely expected devaluation of the bolivar currency and a proposed amnesty for Chavez's jailed and exiled political foes.
"The nation is paralyzed," said Jorge Botti, head of the main private business group, Fedecamaras, urging the government to boost sales of dollars through its currency-control system.
The lack of dollars has left merchants struggling to import products and pushed the black market rate for the bolivar currency to four times its official rate of 4.3.
Venezuelans have been expecting a currency devaluation around the New Year, though Chavez's illness has thrown this in doubt.
Maduro is a committed socialist who has espoused Chavez's views on the international stage for the last six years, including his vitriol against Washington.
He has indicated he would follow Chavez's main policies, including heavy state control of the economy.
"Currency controls have worked well, and yes, they can be improved, they are going to be improved," Maduro said.
Western investors have increasingly shunned Venezuela under Chavez — especially given his nationalizations of large swathes of the economy — giving companies from China, Russia, Iran, Belarus, and other allies a chance to grab footholds.
