81-year-old Castro handed over control to his 76-year-old brother Raśl when he underwent surgery in July 2006. "It would betray my conscience to take up a responsibility that requires mobility and total devotion, that I am not in a physical condition to offer," Castro explained.
Castro, 81, has not appeared in public for 19 months since suffering an undisclosed illness and the Cuban National Assembly is expected to nominate his younger brother Raul as president in his place.
Cuba's National Assembly speaker Ricardo Alarcon had said that while his recovery is ongoing, it was up to Fidel Castro to decide whether he will stay on as president, if reelected in February.
In the past decade, Castro's health deteriorated. In 2004, he made international headlines when he tripped and fell at a graduation ceremony, breaking his left knee and suffering a hairline fracture in his upper right arm.
