How many members are there in the House of Commons?

The House of Commons has a total of 650 members, known as Members of Parliament (MPs). Each MP represents a single parliamentary constituency in the United Kingdom. The number of constituencies, and thus the number of MPs, can be influenced by various factors, including population changes and the redistribution of parliamentary boundaries. The figure of 650 has been established to ensure that representation remains effective and is aligned with the population distribution across the UK, enabling efficient governance and balanced representation from all parts of the country.
