Britain's shadow chancellor George Osborne stands in front of the Conservative Party's slogan as he arrives at its Spring Forum at Cheltenham racecourse, western England April 26, 2009. Britain's opposition Conservatives have a strong lead in opinion polls as people lose faith in the Labour government, but leader David Cameron still has to convince voters he has the policies to rule. Conservatives admit however that public disillusionment may not be enough to secure victory in an election which must be called by June 2010.
