The Cuban Communist Party was later renamed as the People's Socialist Party for electoral reasons. Its policy was dictated from Moscow. At one time, it supported the dictatorship of Gerardo Machado. Later it supported Fulgencio Batista, in whose government Dr. Juan Marinello and Carlos Rafael Rodriguez were ministers without portfolio. Although covert communist support was given to Castro and Che Guevara in the Sierra Maestra, the People's Socialist Party was officially critical of Fidel Castro's rise to power until the summer of 1958.
