Book excerpt: From the Sunday Times bestselling author Which fifty people made Britain the wreck she is? From ludicrous propagandist Alastair Campbell to the Luftwaffe's allies, the modernist architects, it's time to name the guilty. Quentin Letts sharpens his nib and stabs them where they deserve it, from TV gardener Alan Titchmarsh, the dumbed-down buffoon who put the 'h' in Aspidistra, to the perpetrators of the 'Credit Crunch'. Margaret Thatcher ruptured our national unity. The creators of EastEnders trashed our brand over high tea. Thus, he argues, are the people who made our country the ugly, scheming, cheating, beer-ridden bum of the Western world. Here are the fools and knaves and vulgarians who ripped down our British glories and imposed the tawdry and the trite. In a half century we have gone from end-of-Empire to descent-into-Hell.
