Parliament is responsible for making and repealing laws in the UK and for scrutinizing the work of the Government. It consists of the House of Commons with 659 elected MPs, the House of Lords with around 700 unelected members, and the Queen. The main roles of Parliament are to pass laws, provide funding for the government through taxation, scrutinize policies and spending, and debate important issues. Elections are held to select MPs for the House of Commons, with the party that wins most seats forming the government.
