Britain uses a majoritarian First Past the Post system where the UK is divided into 650 constituencies, each with one Member of Parliament (MP).
People have one vote for one MP to sit in the UK Parliament in Westminster and represent their constituency.
The candidate with the most votes is elected into parliament.
The British political system is a multiple-party system.
Since the 1920s, the two dominant parties have been the Conservative Party and the Labour Party.
Before the Labour Party rose in British politics, the Liberal Party was the other major political party, along with the Conservatives.
The government is led by the prime minister (currently Rishi Sunak, since 25 October 2022) who selects all the other ministers.
The country has had a Conservative-led government since 2010, with successive prime ministers being the then-leader of the Conservative Party.
