Madagascar elects on national level a head of state - the president - and a legislature. The president is elected for a five-year term by the people. The Parliament has two chambers. The National Assembly (Antenimieram-Pirenena/Assemblée Nationale) has 127 members (160 before 2007), elected for a four-year term in single-member and two-member constituencies. The Senate (Sénat) has 90 members, 60 members elected for a six-year term, 10 for each province by provincial electors, and 30 members appointed. Madagascar has a one-party dominant system, in which it is difficult for small parties to gain any power.
