Singapore is a parliamentary republic with a Westminster system of unicameral parliamentary government representing constituencies. The country's constitution establishes a representative democracy as the political system. Executive power rests with the Cabinet of Singapore, led by the Prime Minister and, to a much lesser extent, the President. The President is elected through a popular vote, and has veto powers over a specific set of executive decisions, such as the use of the national reserves and the appointment of judges, but otherwise occupies a largely ceremonial post.
The Parliament serves as the legislative branch of the government. Members of Parliament (MPs) consist of elected, non-constituency and nominated members. Elected MPs are voted into the Parliament on a "first-past-the-post" (plurality) basis and represent either single-member or group representation constituencies. The People's Action Party has won control of Parliament with large majorities in every election since self-governance was secured in 1959.
