2006–2008 Cuban transfer of presidential duties

The 2006–2008 Cuban transfer of presidential duties was the transfer of the title of president and presidential duties from longtime Cuban leader Fidel Castro to his brother, First Vice President Raúl Castro, the next-in-line-of-succession person in Cuba, following Fidel's operation and recovery from an undisclosed digestive illness believed to be diverticulitis. Although Raúl Castro exercised the duties of president, Fidel Castro retained the titles of president of the Council of State of Cuba (head of state), president of the Council of Ministers of Cuba (head of government) and first secretary of the Communist Party of Cuba (de facto leader) during this period.
