Political parties in the United Kingdom play a crucial role in the democratic process. The main parties include the Conservative Party, Labour Party, Liberal Democrats, and Scottish National Party (SNP). Each party has its own policies and ideologies, representing a range of views from conservative to progressive. Elections in the UK are primarily held for the House of Commons, where Members of Parliament (MPs) are elected. Political parties campaign to gain seats, and the party with the majority typically forms the government. This system allows citizens to choose their representatives and influence national policies.
