The Parliament of Singapore is the unicameral legislature of the Republic of Singapore, which governs the country alongside the President of Singapore. Based on the Westminster system, it consists of elected Members of Parliament (MPs), non-constituency MPs (NCMPs) and Nominated MPs (NMPs). Following the 2025 general election, 97 MPs from two political parties, the governing People's Action Party (PAP) and the opposition Workers' Party (WP), were elected to the 15th Parliament. 2 NCMPs from the latter were also appointed ("elected" in the language of Singaporean law). Nine NMPs are usually appointed by the president on a biennial basis.
The Speaker of Parliament presides over sittings and oversees the administration of Parliament. The Leader of the House is appointed by the prime minister to manage government business and the legislative programme, while the Leader of the Opposition leads the largest political party not in government. Some work is carried out by select committees of MPs. Standing committees are permanent, while ad hoc committees are established to examine specific matters, including bills. Selected backbenchers of the PAP serve on Government Parliamentary Committees (GPCs) to review policies, programmes, and proposed legislation of government ministries.
