The UK Committee on Standards in Public Life was set up in October 1994 and issued its first report in 1995, under the chairmanship of Lord Nolan. It was established in order to investigate concerns about the conduct of members of parliament, after allegations that MPs had taken cash for putting down parliamentary questions. The Committee Report set out seven principles of public life: selflessness, integrity, objectivity, accountability, openness, honesty, and leadership. The ‘Nolan reforms’ established a new post of Parliamentary Commissioner for Standards (see ombudsman) whose job was to maintain the Register of Members' Interests and investigate the conduct of MPs; to set up a House of Commons Committee on Standards and Privileges; and to set down a Code of Conduct for MPs. In 1998 the Committee issued a report on the funding of political parties, which rejected calls for state funding.
