Georgia is governed under the constitution of 1995 as amended. The president, who is head of state and has direct control over government bodies responsible for national security and defense, is elected by popular vote for a five-year term and is eligible for a second term. The prime minister, who is head of government, is responsible for managing the nation's economic policies. The unicameral legislature consists of the 150-seat Parliament (or Supreme Council); 75 members are elected on a proportional basis and 75 are directly elected by districts. All serve five-year terms. Administratively, the country is divided into nine regions, one city, and two autonomous republics.
