Jordan is a constitutional monarchy. Under the 1952 constitution as amended, the most powerful political and military figure in the country is the king, who is head of state. The government is headed by the prime minister, who is appointed by the monarch. The bicameral parliament consists of the 75-seat Chamber of Notables, or Senate, whose members are appointed by the king, and the 150-seat House of Deputies, whose members are popularly elected, with six seats reserved for women. Electoral constituencies, however, are gerrymandered in favor of the government. All legislators serve four-year terms. Administratively, Jordan is divided into 12 governorates.
