Jordan is a unitary constitutional monarchy. Executive authority is exercised through the Council of Ministers, led by the Prime Minister, in accordance with the Constitution. Legislative authority is vested in the bicameral National Assembly, which consists of the Senate (Majlis Al-Ayan) and the House of Representatives (Majlis Al-Nuwaab). Judicial authority is exercised by independent courts. Administratively, Jordan is divided into twelve governorates. While local councils perform certain administrative functions, political decision-making and legislative authority remain largely centralized at the national level.
