Brazil is governed under the 1988 constitution as amended. The president, who is elected by popular vote for a four-year term (and may serve two terms), is both head of state and head of government. There is a bicameral legislature consisting of an upper Federal Senate and a lower Chamber of Deputies. The 81 senators are elected for eight years and the 513 deputies are elected for four years. The president may unilaterally intervene in state affairs. Administratively, the country is divided into 26 states and one federal district (Brasília); each state has its own governor and legislature. The main political parties are the Brazilian Democratic Movement party, the Liberal Front party (now known as the Democrats party), the Democratic Labor party, the Brazilian Social Democracy party, and the Workers party.
