After assuming what was envisioned as a temporary control over the presidency in 2006, on 24 February 2008 Raúl Castro won election as the new President of the Council of State and President of the Council of Ministers during a legislative session held at Cuba's Palace of Conventions in Havana.
In a February 2008 letter, Castro announced that he would not accept the positions of President of the Council of State and Commander in Chief at that month's National Assembly meetings, remarking, "It would betray my conscience to take up a responsibility that requires mobility and total devotion, that I am not in a physical condition to offer". On 24 February 2008, the National Assembly of People's Power unanimously voted Raúl as president. Describing his brother as "not substitutable", Raúl proposed that Fidel continue to be consulted on matters of great importance, a motion unanimously approved by the 597 National Assembly members.
