The politics of Vietnam are dominated by a single party, the Communist Party of Vietnam (CPV). The President of Vietnam is the head of state, and the Prime Minister of Vietnam is the head of government, both of these are separate from the General Secretary of the Communist Party of Vietnam who leads the Communist Party and is head of the Politburo and the Central Military Commission, thus the General Secretary is the de facto supreme leader of Vietnam. Executive power is exercised by the government and the President of Vietnam. Legislative power is vested in the National Assembly of Vietnam (Vietnamese: Quốc hội Việt Nam). The Judiciary is independent of the executive. The parliament adopted the current Constitution of Vietnam, its fifth, on 28 November 2013.
