The Cuban government has appointed the first vice president Miguel Diaz-Canel as sole candidate for president.
The movement guarantees that the 57-year-old engineer will succeed General Raul Castro, 86.
Wednesday's announcement confirms the long-standing expectation that Diaz-Canel would take over from Castro in a transition to ensure that the country's single party system exceeds the aging revolutionaries who created it.
The nomination must now be approved by the 604 delegates participating in the National Assembly, who always approve nominations with total or almost unanimous voting.
Nominated as new first vice president is Salvador Valdes Mesa, a 72-year-old Afro-Cuban former trade unionist who has had a large number of high posts in the Cuban government.
Castro leaves his post after earning two five-year terms.
He succeeded his brother Fidel, who led Cuba from 1959 to 2006.
