Eritrea is governed under the transitional constitution of 1993. A new constitution was adopted in 1997 but it has not been fully implemented. The executive branch is headed by the president, who is both head of state and head of government; the president is elected by the National Assembly for a five-year term and is eligible for a second term. There is a unicameral 150-seat National Assembly whose members are to be popularly elected, but legislative (and presidential) elections scheduled for 2001 were not held. Administratively, the country is divided into six regions.
