The former guerrilla fighters who founded Cuba’s single-party government will hold power for years to come after a twice-a-decade Communist Party congress kept President Raul Castro and his hard-line deputy in the top leadership positions.

Fidel Castro, who held power for nearly five decades before ill health led him to make way for his brother, delivered a valedictory speech to the congress Tuesday and called on it to fight for his communist ideals despite the fact that he is nearing the end of his life.
