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. Freedom House ranks Singapore as "partly free" in its Freedom in the World report and The Economist ranks Singapore as a "flawed democracy", the second best rank of four, in its "Democracy Index".
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.
