Book excerpt: The struggle between the main political parties has been reduced to an unpopularity contest, in which voters hold their noses and sigh as they trudge to the polls. Peter Hitchens explains how and why British politics has sunk to this dreary level - the takeover of the parties and the media by conventional left-wing dogmas which then call themselves 'the centre ground'. The Tory party under David Cameron has become a pale-blue twin of New Labour, offering change without alteration. Hitchens, a former Lobby reporter, examines and mocks the flock mentality of most Westminster journalists, explains how unattributable lunches guide coverage and why so many reporters - once slavish admirers of Labour - now follow the Tory line. This updated edition of Hitchens's The Broken Compass (2009) features a brand new introduction. In an excoriating analysis, Hitchens examines the Tory Party's record in government and opposition, dismissing it as a failure on all fronts but one - the ability to win office without principle. The one thing it certainly isn't is conservative.
