Chile is governed under the constitution of 1981 as amended. It is a multiparty democracy with a directly elected president who serves a four-year term (six-year prior to the constitutional amendments of 2005). The president may not be elected to consecutive terms. The bicameral legislature consists of a 38-seat Senate, whose members are elected to serve eight-year terms, and a 120-seat Chamber of Deputies, whose members are elected for four years. Members of both houses are elected from two-seat districts. Administratively, Chile is divided into 13 regions.
