Ukraine is governed under the constitution of 1996. The president, who is the head of state, is popularly elected for a five-year term and is eligible for a second term. The government is headed by the prime minister, who along with the cabinet is named by president. The unicameral legislature consists of the 450-seat Supreme Council (Verkhovna Rada), whose members are elected to serve five-year terms. All parties that win at least 3% of the national vote in the parliamentary election are awarded seats on a proportional basis. Administratively, Ukraine is divided into 24 provinces or oblasts, two municipalities with oblast status (Kiev and Sevastopol), and one autonomous republic (Crimea).
