Greece is governed under the constitution of 1975 as amended. The president, who is the head of state, is elected by the legislature for a five-year term and is eligible for a second term. The premier, who is the head of government, is appointed by the president with the approval of Parliament, as is the cabinet. The 300 members of the unicameral Parliament are popularly elected to four-year terms. Administratively the country is divided into 13 regions (which are subdivided in 325 municipalities) and the autonomous monastic state of Mt. Athos.
