I want a Britain that is one nation, with shared values and purpose, where merit comes before privilege, run for the many not the few, strong and sure of itself at home and abroad.

One day, meandering through the bookcases, I had picked up his diaries and begun to read the account of his famous meeting with Hitler prior to Munich, at the house in Berchtesgaden high up in the Bavarian mountains. Chamberlain described how, after greeting him, Hitler took him up to the top of the chalet. There was a room, bare except for three plain wooden chairs, one for each of them and the interpreter. He recounts how Hitler alternated between reason – complaining of the Versailles Treaty and its injustice – and angry ranting, almost screaming about the Czechs, the Poles, the Jews, the enemies of Germany. Chamberlain came away convinced that he had met a madman, someone who had real capacity to do evil. This is what intrigued me. We are taught that Chamberlain was a dupe; a fool, taken in by Hitler’s charm. He wasn’t. He was entirely alive to his badness. I tried to imagine being him, thinking like him. He knows this man is wicked; but he cannot know how far it might extend. Provoked, think of the damage he will do. So, instead of provoking him, contain him. Germany will come to its senses, time will move on and, with luck, so will Herr Hitler. Seen in this way, Munich was not the product of a leader gulled, but of a leader looking for a tactic to postpone, to push back in time, in hope of circumstances changing. Above all, it was the product of a leader with a paramount and overwhelming desire to avoid the blood, mourning and misery of war. Probably after Munich, the relief was too great, and hubristically, he allowed it to be a moment that seemed strategic not tactical. But easy to do. As Chamberlain wound his way back from the airport after signing the Munich Agreement – the fateful paper brandished and (little did he realise) his place in history with it – crowds lined the street to welcome him as a hero. That night in Downing Street, in the era long before the security gates arrived and people could still go up and down as they pleased, the crowds thronge

you have to be able to answer those questions plainly and clearly. There can be qualifications and “get-outs,” but the answers must remain comprehensible, because they define you. They add up to a political, not merely personal, character. This requires thought, detailed analysis and intellectual rigour. Politics is a far more intellectual business than is often realized. You may think: Well, if it’s simplicity that’s required, you don’t need a whole lot of detail. Wrong. The simplicity is not born of superficial analysis. It is simple precisely because it is the product of being worked through.
