Government of Cuba

Cuba has had, according to the Constitution, a democratic centralist political system since 1959 based on the "one state – one party" principle. Cuba is constitutionally defined as a Marxist–Leninist "socialist state guided by the political ideas of Marx, one of the fathers of historical materialism, Engels and Lenin". The present Constitution also ascribes the role of the Communist Party of Cuba to be the "leading force of society and of the state" and as such has the capability of setting national policy.

Executive power is exercised by the Government, which is represented by the Council of State and the Council of Ministers. Legislative power is exercised through the unicameral National Assembly of People's Power, which is constituted as the maximum authority of the state. Currently Raúl Castro—brother of former President Fidel Castro—is President of the Council of State, President of the Council of Ministers (sometimes referred to as the Prime Minister), First Secretary of the Communist Party, and Commander-in-Chief of the Revolutionary Armed Forces. Fidel Castro has ruled from 1959 to 2016 before his brother took the power. Esteban Lazo Hernández is President of the National Assembly.
