There's people on the left who say, the ballot box is a waste of time. Forget them. When Mandela voted for the first time at the age of 76 there was a lot of grown men, including me, wept buckets. That was what it was about. It doesn't solve things, but it gives you the mechanism to hold to account the people with power.

If democracy is destroyed in Britain, it will be not the communists, Trotskyists or subversives but this House which threw it away. The rights that are entrusted to us are not for us to give away. Even if I agree with everything that is proposed, I cannot hand away powers lent to me for five years by the people of Chesterfield. I just could not do it. It would be theft of public rights.

I was radicalised by being a minister. That's when I saw how the system really worked. And that is not a very usual process, but it certainly happened to me: it gave me a lot more experience, it helped me to understand where power really lay, develop strategies for undermining or changing it, and so on. But that isn't the norm. Mr Gladstone moved to the left as he got older, and one or two other people have, but normally you swing the other way.

If one meets a powerful person--Adolf Hitler, Joe Stalin or Bill Gates--ask them five questions: "What power have you got? Where did you get it from? In whose interests do you exercise it? To whom are you accountable? And how can we get rid of you?

If you file your waste-paper basket for fifty years, you have a public library.

I have had the advantage of a radical Christian upbringing

I think to understand how the democratic process works is the most important thing, so people don't get frightened by it, and get put off, and give up.
