Cuban officials did not immediately respond to a request for comment.

Rumors have suggested as a possible successor Foreign Minister Bruno Rodriguez, who last week was promoted to the Communist Party's powerful Political Bureau.


Alarcon was Cuba's ambassador to the United Nations in 1966-1978 and 1990-1992, and served as vice president of the U.N. General Assembly.

Well-spoken and with a perfect command of English, for many years he has been Cuba's go-to guy on U.S. relations. He represented Havana in talks with Washington, Cuba's battle for the return of young raft boy Elian Gonzalez in 2000 and its campaign to demand the return of five Cuban intelligence agents serving long prison sentences in the U.S.

If a younger political leader steps into his job, it would be among the most high-profile replacements to date touching the "historic" generation that has surrounded Fidel and Raul Castro in power since the 1959 revolution.

"Not so much because of the National Assembly job but because of who he is," Peters said. "He was part of the revolutionary movement in the 1950s and became one of Cuba's top diplomats and the preeminent expert on the United States, and was relied upon for many years for that."

Other younger faces have recently been tapped for prominent positions such as Murillo, who is leading Raul Castro's economic reforms, and Lazara Mercedes Lopez Acea, who became Communist Party boss in Havana in 2009.

In March, Diaz-Canel, a former higher education minister in his 50s, replaced an 88-year-old former general who had been the oldest vice president on Castro's Council of Ministers.

Whispers of Alarcon's departure have been around for months, and they intensified this summer amid rumors that his right-hand man, Miguel Alvarez, and Alvarez's wife had been arrested in a probe of alleged corruption.

However there has been no confirmation of the arrest, nor evidence that Alarcon was a target of an investigation or had otherwise fallen out of favor.

The current legislature is nearing the end of its five-year term. It reconvenes in February and is expected to name Raul Castro to a new term as president.
