Members of the House of Commons in the United Kingdom are selected through a process known as general elections, which typically occur every five years. Each Member of Parliament (MP) represents a specific constituency and is elected by the local populace through a system called First Past the Post. The candidate who receives the most votes within their constituency wins. This electoral system emphasizes individual candidates rather than political parties, often resulting in a significant concentration of power among the leading parties, affecting the overall composition of the House.
