Legislative power is divided between federal and state legislatures. The bicameral federal parliament consists of the lower house, the House of Representatives and the upper house, the Senate. The 222-member House of Representatives is elected for a maximum term of five years from single-member constituencies. All 70 senators sit for three-year terms; 26 are elected by the 13 state assemblies, and the remaining 44 are appointed by the King upon the Prime Minister's recommendation. The parliament follows a multi-party system and the government is elected through a first-past-the-post system. Since independence Malaysia has been governed by a multi-party coalition known as the Barisan Nasional.
