Parliament is the legislative body of the UK government. It is responsible for creating laws, taxation, oversight of government policy and administration, and debating important issues. General elections are held every 5 years, where eligible registered voters in each of the 650 constituencies vote for the candidate they want to represent their area as a Member of Parliament in the House of Commons. The party with the most MPs after the election usually forms the government. If no party has an overall majority, a coalition government between two or more parties may be formed.
