Overview
The prime minister of Singapore is the head of government of the Republic of Singapore. The president appoints the prime minister, a Member of Parliament (MP) who in their opinion, is most likely to command the confidence of the majority of MPs. The incumbent prime minister is Lee Hsien Loong, who took office on 12 August 2004.
Singapore is modelled after the Westminster system. The prime minister only governs with the confidence of the majority in Parliament; as such, the prime minister typically sits as a Member of Parliament (MP) and leads the largest party or a coalition of parties. In practice, the prime minister is the leader of the majority party in Parliament.
History
The office of Prime Minister succeeded the office of Chief Minister in 1959 after Singapore had attained self-governance from the United Kingdom, as the State of Singapore, with Lee Kuan Yew being sworn in as the first prime minister on 5 June 1959.
With respect to Singapore's autonomous status in the Malaysia Agreement, the title of prime minister remained unchanged after Singapore's merger with Malaya, Sarawak and North Borneo to form Malaysia in 1963, despite the existence of the prime minister of Malaysia for the entire federation of which Singapore was briefly a part of.
