1.1 Ministers of the Crown are expected to behave according to the highest standards of constitutional and personal conduct in the performance of their duties.
1.2 This Code provides guidance to Ministers on how they should act and arrange their affairs in order to uphold these standards. It lists the principles which may apply in particular situations drawing on past precedent. It applies to all members of the Government (and covers Parliamentary Private Secretaries in section 2).
1.3 Ministers are personally responsible for deciding how to act and conduct themselves in the light of the Code and for justifying their actions and conduct in Parliament. The Code is not a rulebook, and it is not the role of the Secretary of the Cabinet or other officials to enforce it or to investigate Ministers although they may provide Ministers with private advice on matters which it covers.
1.4 Ministers only remain in office for so long as they retain the confidence of the Prime Minister. He is the ultimate judge of the standards of behaviour expected of a Minister and the appropriate consequences of a breach of those standards, although he will not expect to comment on every allegation that is brought to his attention.
1.5 The Code should be read against the background of the overarching duty on Ministers to comply with the law, including international law and treaty obligations, to uphold the administration of justice and to protect the integrity of public life. They are expected to observe the Seven Principles of Public Life set out in the first report of the Committee on Standards in Public Life, repeated in annex A, and the following principles of Ministerial conduct:
1.6 Ministers must also comply at all times with the requirements which Parliament itself has laid down, including in particular the Codes of Conduct for their respective Houses. For Ministers in the Commons, these are set by the Resolution carried on 19 March 1997 (Official Report columns 1046-47), and for Ministers in the Lords the Resolution can be found in the Official Report of 20 March 1997 column 1057.
