"I watched again the latest of the Prime Minister's departure announcements. It was the point at which he told us - hanging unspoken the story of his disastrous adventure in Iraq - that, yes, he'd made the odd mistake. 'But I ask you to accept one thing,' he said. 'Hand on heart, I did what I thought was right.'
"And there it was: 'Heart nav directed me into path of train.' The thing is, I think he's telling - more or less - the truth. I don't doubt his sincerity, his self-belief, his unwavering conviction in the purity of his own intentions. But you could see the whole decade-long shebang as having been an education for him in the fact that sincerity and self-belief are necessary but not sufficient qualities for government: that you don't just need to follow the heart nav; you need to read the instructions at the level-crossing, too." —Sam Leith
