The document summarizes the British system of government. It notes that the United Kingdom is a constitutional monarchy, with the Queen as head of state but expected to remain politically neutral. Ultimate authority lies with Parliament, consisting of the House of Commons and House of Lords. The House of Commons is the more powerful body, elected by citizens over 18 through general elections every five years. It oversees legislation and government. The party with the most seats forms the government and their leader becomes Prime Minister.
