The Conservatives are largely responsible for their present plight. Ukip may profess contempt for the Tory Party, but it is one of its products. The Conservative leadership and its press supporters always believed, like many right-wing toffs in the past, that they could control any insurgency their political tactics might evoke. For the last few years the Tory Party and its cheerleaders in the Mail, the Sun, the Express and (a little more decorously) the Telegraph have cultivated a populist rhetoric – xenophobic, anti-European, anti-trade union, anti-welfare – as extreme as anything we have known. And they have assumed that such rhetoric could be managed for the benefit only of the ruling circles within the party. But for several years it has been clear – not least to David Cameron – that this assumption is wrong.
