After handing over power to his successor, Raul Castro will remain as a deputy to the parliament and as the first secretary of the Central Committee of the ruling Communist Party of Cuba, which is considered as the leading force of the Cuban society. First Vice President Miguel Diaz-Canel, 57, is widely seen to be Raul Castro's successor.
