Passage: A Freedom of Information request in 2005 revealed that Eton had received 2,652 in farming subsidies in 2004 under the Common Agricultural Policy. Asked to explain under what grounds it was eligible to receive farming subsidies, Eton admitted that it was 'a bit of a mystery'. The TaxPayers' Alliance also stated that Eton had received a total of 5,300 in CAP subsidies between 2002 and 2007. Panorama revealed in March 2012 that farming subsidies were granted to Eton for 'environmental improvements', in effect 'being paid without having to do any farming at all'.
In what year was the Taxpayers' Alliance established?
