Ongoing political agitation for greater
self-governance in Singapore intensified during the 1950s. Chief Minister
David Marshall, who led the
Labour Front government formed after the
1955 general election, initiated constitutional talks with the British government in 1956. However, his first delegation to
London failed to secure full internal self-government due to concerns over Singapore's political stability and public order. Marshall resigned following this failure, as he had pledged to do if the mission was unsuccessful. His successor,
Lim Yew Hock, adopted a more hardline approach to internal security and took action against
left-wing trade unions and pro-communist elements, measures that reassured the British authorities of Singapore's administrative capability. Under Lim's leadership, renewed negotiations with the British culminated in the 1958 Constitutional Agreement, formally known as the Singapore (Constitution) Order in Council 1958. This agreement led to amendments to the Constitution, providing for a fully elected Legislative Assembly with 51 seats and granting the colony full internal self-government, except in the areas of defence and foreign affairs, which remained under British control. The new constitutional framework took effect after the
1959 general election, in which the
People's Action Party (PAP) won a decisive victory. This marked the beginning of self-governing rule under
Lee Kuan Yew with the newly created position of
Prime Minister. The Legislative Assembly, now operating with significantly expanded powers, functioned as the primary law-making body of the state. Following
Singapore's separation from Malaysia and the declaration of independence on 9 August 1965, the Legislative Assembly was formally reconstituted as the
Parliament of Singapore under the country's new constitutional framework. The existing members of the Assembly became the first Members of Parliament (MPs), ensuring institutional continuity as a newly sovereign nation. == List of sessions ==
