First the Suez crisis, then the invasion of Iraq. And now this referendum

In the catalogue of catastrophic misjudgments made by prime ministers, what David Cameron has done to Britain ranks very high

'Here we are, and the question is: where do we go from here?" Thus spoke one of David Cameron's (and my) political heroes, after a crisis that bore little comparison with the ordeal that our prime minister has recently put us all through.
