Members of Parliament, or MPs, are elected representatives in a country's legislative body. Their primary role is to create, debate, and vote on laws that govern the nation. MPs represent the interests of their constituents, the people who live in their electoral district, and are responsible for voicing their concerns in Parliament. In many countries, MPs are part of a larger political party, which helps to shape their policies and decisions. They also participate in committees that focus on specific issues, such as health, education, or finance, ensuring that various aspects of society are addressed in the legislative process.
