Moves a Bill to provide for statutory codes of conduct for Ministers of the Crown, Members of Parliament, members of the House of Lords, and councillors in England. Emphasises the importance of integrity, probity, and adherence to the Nolan principles. Criticises the current system's lack of independence and transparency, particularly regarding investigations into breaches of the ministerial code by the Prime Minister. Proposes the establishment of an independent commissioner on ministerial standards and a statutory office for the Parliamentary Commissioner for Standards with broader investigative powers.
