Policy Exchange is a British conservative think tank based in London. The Daily Telegraph has described it as "the largest, but also the most influential think tank on the right". The New Statesman named it as David Cameron's "favourite think tank", a view shared by the Political Editor of the Evening Standard Joe Murphy, who referred to it as "the intellectual boot camp of the Tory modernisers’". Its alumni include Anthony Browne, one of London Mayor Boris Johnson’s policy directors, and a number of the Conservative 2010 intake of MPs. More information on the Wikipedia page [1].
