The current system of governance, since the Constitution 18 July 1999, is termed the Fifth Republic of Niger. It is a semi-presidential republic, whereby the President of Niger is head of state and the Prime Minister of Niger head of government. The officials holding these posts are chosen through a representative democratic process of national and local elections, in the context of a competing multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly. The judiciary is independent of the executive and the legislature: its Constitutional Court has jurisdiction over constitutional and electoral matters.
