Malaysia is a multi-party system since the first direct election of the Federal Legislative Council of Malaya in 1955 on a first-past-the-post basis. The ruling party since then has always been the Alliance Party coalition and subsequently from 1973 onwards, its successor the National Front coalition. The National Front currently consists of the United Malays National Organisation (UMNO), Malaysian Chinese Association (MCA), Malaysian Indian Congress (MIC) and 11 other political parties. Malaysia is a federal constitutional elective 
monarchy. The federal head of state of Malaysia is the Yang di-Pertuan Agong, commonly referred to as he 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 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. Registered voters of age 21 and above may vote for the members of the House of Representatives and in most of the states, the state legislative chamber as well. Voting is not compulsory.Executive power is vested in the cabinet led by the prime minister; the Malaysian constitution stipulates that the prime minister must be a member of the lower house of parliament who, in the opinion of the Yang di-Pertuan Agong, commands a majority in parliament. The cabinet is chosen from among members of both houses of Parliament and is responsible to that body. 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 each of the states with a hereditary ruler, the Chief Minister is required to be a Malay Muslim, although this rule is subject to the rulers' discretion. The Constitution of Malaysia is codified and the system of government is based on the Westminster system. Although Malaysian politics has been relatively stable, critics allege that "the government, ruling party, and administration...are intertwined with few countervailing forces
