Who oversees the behaviour of MPs and ensures they adhere to the Code of Conduct?

The Parliamentary Commissioner for Standards is responsible for overseeing the behaviour of Members of Parliament (MPs) and ensuring they adhere to the Code of Conduct. This role involves investigating complaints about MPs' conduct, particularly concerning breaches of the Code, which outlines the ethical standards expected from them. The Commissioner investigates such cases independently and reports findings to the House of Commons.

The Parliamentary Commissioner for Standards plays a crucial role in maintaining accountability and integrity in Parliament, thereby fostering public trust in democratic institutions. This role has specific powers to enforce rules and recommend disciplinary actions, contributing to a more transparent political environment.

While other figures, such as the Speaker of the House, the Independent Parliamentary Standards Authority, and the Prime Minister, have distinct functions in the parliamentary system, they do not directly oversee the behaviour of MPs regarding adherence to the Code of Conduct. The Speaker facilitates debates and ensures parliamentary rules are followed, the Independent Parliamentary Standards Authority manages MPs' expenses and remuneration rather than conduct, and the Prime Minister's authority is more about governance than directly overseeing individual MP behaviours.
