The Committee of Public Accounts is a select committee of the British House of Commons. It is responsible for overseeing government expenditures, and to ensure they are effective and honest. The committee is seen as a crucial mechanism for ensuring transparency and accountability in government financial operations, having been described by Professor the Lord Hennessy as "the queen of the select committees...[which] by its very existence exert[s] a cleansing effect in all government departments".^[1]

The recommendation for the creation of a committee to oversee government accounts was first put forward in 1857 by a small group of interested Members of Parliament led by Sir Francis Baring. The structure and function of the PAC date back to reforms initiated by William Ewart Gladstone, when he was British Chancellor of the Exchequer in the 1860s. The first Public Accounts Committee was established in 1862 by a resolution of the British House of Commons:

There shall be a standing committee designated "The Committee of Public Accounts"; for the examination of the Accounts showing the appropriation of sums granted by Parliament to meet the Public Expenditure, to consist of nine members, who shall be nominated at the commencement of every Session, and of whom five shall be a quorum.^[2]

The form has since been replicated in virtually all Commonwealth of Nations and many non-Commonwealth countries. A minister from His Majesty's Treasury sits on the committee but, by convention, does not attend hearings. The Chair of the committee is always drawn from the main opposition party and is usually a former senior Minister.

The Exchequer and Audit Departments Act 1866 appointed The Committee of Public Accounts to oversee the work of the Comptroller and Auditor General (C&AG)^[3] The Committee continues to be assisted by the C&AG who is a permanent witness at its hearings, along with his staff of the National Audit Office, who provide briefings on each report and assist in the preparation of the Committee's own reports.

The Committee's members as of December 2023 are as follows:^{[4][5][6][7][8][9] [10]}

The chair was elected on 10 June 2010, with members being announced on 12 July 2010.^[17][18]

House of Commons standing orders give the party of the official Opposition the right to chair the committee.^[19]
