United Kingdom parliamentary expenses scandal

The United Kingdom parliamentary expenses scandal was a major political scandal that emerged in 2009, concerning expense claims made by members of the British Parliament in both the House of Commons and the House of Lords over the previous years. The disclosure of widespread misuse of allowances and expenses permitted to members of Parliament (MPs) aroused widespread anger among the UK public and resulted in a large number of resignations, sackings, de-selections, and retirement announcements, together with public apologies and the repayment of expenses. Several members, and former members, of both the House of Commons and the House of Lords were prosecuted and sentenced to terms of imprisonment.

A February 2008 Freedom of Information Act request for the release of details of MPs' expense claims was allowed by an Information Tribunal and was challenged by the House of Commons Authorities on the grounds that it was "unlawfully intrusive". In May 2008, the High Court (England and Wales) ruled in favour of releasing the information. In April 2009, the House of Commons authorities announced that publication of expenses, with certain information deemed "sensitive" redacted, would be made available in July 2009. However, before this could take place, the expenses' records and documentation were leaked to The Daily Telegraph newspaper, which began publishing details in daily instalments from 8 May 2009. These disclosures dominated the British media for weeks. On 18 June 2009, the details of all MP expenses and allowance claims approved from 2004 to 2008 were published on the official Parliament website, but with some details removed, such as addresses, claims that were not approved for payment, and correspondence between MPs and the parliamentary fees office. This brought further accusations of unnecessary secrecy and allegations that this might have prevented serious abuses from being disclosed.
