During his lifetime he enjoyed secret chats with Winston Churchill, studied briefly under the philosopher Heidegger, intercepted personal messages between Hitler and Rommel, hung out with the Beatles in Carnaby Street, and even set up fashion guru Paul Smith with his first shop.
Here he talks about subversives in Britain and America, and the fact that every leader in Britain from Heath onwards were traitors to Britain. And - as a MI6 Colonel - he should know.
The first hour is his fascinating speech, without notes, and the second half, is a question and answer time. If you don't have two hours to spare, I implore you to watch the first half.
His autobiography is available on Amazon UK for £18.94 and has only been produced on paperback. I'm saving up!
