The Parliament serves as the legislative branch of government. Members of Parliament (MPs) are made up of elected, non-constituency and nominated members. Elected MPs are voted into parliament on a "first-past-the-post" (plurality) system and represent either single-member or group-representation constituencies. Elections are free, and the People's Action Party has won control of Parliament with large majorities in every election since self-governance in 1959. In the most recent parliamentary elections in 2020, the largest opposition, led by the Workers' Party, increased its representation in the House to 10 elected MPs out of 93.
