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.
