The Prime Minister of Malaysia is the chairman of the Cabinet and thus head of government for Malaysia, charged with advising the Yang di-Pertuan Agong on the exercise of the executive powers vested in them by the constitution. It is in practice, the most powerful political position in Malaysia. As stated in the federal constitution, the Yang di-Pertuan Agong shall select as Prime Minister the person most likely to command the confidence of the elected House of Representatives; this individual is typically the leader of the political party that holds the largest number of seats in that chamber.
