The United Kingdom parliamentary expenses scandal was a major political scandal that emerged in 2009, concerning expenses claims made by members of the United Kingdom Parliament 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 or former members of the House of Commons, and members of 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' expenses claims was allowed by an Information Tribunal but 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" removed, would be made in July 2009. But before this could take place the expenses records and documentation were leaked to The Daily Telegraph newspaper, which began publishing details in daily installments from 8 May 2009. These disclosures dominated the British media for weeks. On 18 June 2009 the details of all MPs' expenses and allowance claims approved from 2004 to 2008 were published on the official Parliament website with detail such as addresses, claims that were not approved for payment and correspondence between MPs and the parliamentary fees office removed, bringing further accusations of unnecessary secrecy and allegations that this might have prevented serious abuses from being disclosed.
Since most claims revolved around MP's second homes in London, a panel was established to investigate all claims relating to the "second homes" allowance between 2004 and 2008. Headed by former civil servant Sir Thomas Legg, the panel published its findings on 12 October as MPs returned to Westminster following the summer recess. Each MP received a letter stating whether or not he or she would be required to repay any expenses claimed. Details of voluntary repayments by MPs amounting to almost £500,000 were also officially published.
