HAVANA (Cuba): Cuban President Raul Castro has unexpectedly raised the possibility of leaving his post, saying on Friday that he is old and has a right to retire. But he did not say when he might do so or if such a move was imminent.

The Cuban leader is scheduled to be named by parliament to a new five-year term on Sunday, and Castro urged reporters to listen to his speech that day.    “I am going to resign,” Castro said at a joint appearance with visiting Russian Prime Minister Dmitry Medvedev.

“I am going to be 82 years old,” Castro added, a broad smile on his face. “I have the right to retire, don't you think?”

When reporters continued to shout questions about his plans for the next five years, Castro replied: “Why are you so incredulous?'' He said to listen carefully on Sunday.

“It will be an interesting speech,” he said. “Pay attention.”

Castro’s tone was light and his comments came in informal remarks at a mausoleum dedicated to soldiers from the former Soviet Union who have died around the world.—AP
