Why Mosley failed
Macmillan greeted me gravely, and we lunched together. I noticed on the grand piano, among the clutter of signed photographs of heads of state in silver frames, a copy of Mosley's autobiography, which had just been published.
 
To make conversation, I asked Harold what he thought of Oswald Mosley. Immediately, he came to life: "Ah Tom Mosley, quite the most able man I have ever met, but quite mad. He came to me once and said 'Harold, I'm thinking of putting my people into black shirts.' 'Tom,' I replied, 'you must be mad. Whenever the British feel strongly about anything, they wear grey flannel trousers and tweed jackets.' "
