Havana: Cuban President Raul Castro on Friday unexpectedly raised the possibility of leaving his post, saying he is old and has a right to retire.
But the Cuban leader he did not say when he might do so or whether such a move was imminent.
The Cuban leader is scheduled to be sworn in to a new five-year term on Sunday. And, Castro referred to the speech he is set to make that day, which he promised would be "interesting".
"I am going to be 82 years old," Castro said at a joint appearance with visiting Russian Prime Minister Dmitry Medvedev. "I have the right to retire, don`t you think?"
Castro`s tone was light and his comments came in informal remarks to reporters at a mausoleum dedicated to soldiers from the former Soviet Union who have died around the world.
The Cuban leader has spoken before of his desire to implement a two-term limit for all Cuban government positions, including the presidency. That has led many to speculate that this upcoming term would be his last. He would be 86 when the term ends in 2018.
When Castro does leave the political stage, it would end more than a half century of unbroken rule by him and his brother Fidel, who came to power in 1959 at the head of a revolution against US-backed strongman Fulgencio Batista.
Relations with the US have been sour since shortly after the two came to power. One of the key provisions of the 51-year US economic embargo on Cuba stipulates that it cannot be lifted so long as either of the Castros is in power.
The current president has implemented a series of economic and social reforms since taking over from his ailing brother in 2006, but the island is still ruled by one party. Fidel Castro is 86 and retired.
