Malaysia is a federal constitutional elective monarchy. The federal head of state of Malaysia is the Yang di-Pertuan Agong, commonly referred to as the King of Malaysia. The Yang di-Pertuan Agong is elected to a five-year term among the nine hereditary Sultans of the Malay states; the other four states, which have titular Governors, do not participate in the selection.
The system of government in Malaysia is closely modeled on that of Westminster parliamentary system, a legacy of British colonial rule. In practice however, more power is vested in the executive branch of government than in the legislative, and the judiciary has been weakened by sustained attacks by the government during the Mahathir era. Since independence in 1957, Malaysia has been governed by a multi-party coalition known as the Barisan Nasional (formerly known as the Alliance).
Legislative power is divided between federal and state legislatures. The bicameral parliament consists of the lower house, the House of Representatives or Dewan Rakyat (literally the "Chamber of the People") and the upper house, the Senate or Dewan Negara (literally the "Chamber of the Nation"). The 222-member House of Representatives are elected from single-member constituencies that are drawn based on population for a maximum term of five years. All 70 Senators sit for three-year terms; 26 are elected by the 13 state assemblies, two representing the federal territory of Kuala Lumpur, one each from federal territories of Labuan and Putrajaya, and 40 are appointed by the king. Besides the Parliament at the federal level, each state has a unicameral state legislative chamber (Malay: Dewan Undangan Negeri) whose members are elected from single-member constituencies. Parliamentary elections are held at least once every five years, with the last general election being in March 2008.[40] The cabinet is chosen from among members of both houses of Parliament and is responsible to that body.[44]
State governments are led by chief ministers (Menteri Besar in Malay states or Ketua Menteri in states without hereditary rulers), who is a state assembly member from the majority party in the Dewan Undangan Negeri.In the states with hereditary rulers,the chief ministers are requiered to be a malay muslim.This discriminatory laws had exist since the early 20th century and are yet to be reviewed.
