I used to be very routine-based and the new thing in my life is not having a clear, full-time existence.

I'm certainly driven, I hate losing, I can be ruthless and short-tempered and terribly competitive.

My closest friend, who died not long ago, is buried near Marx's grave in Highgate cemetery, so I see the gaggle of admirers laying roses at the foot of his tombstone regularly. I have never been tempted to leave flowers there myself. Great theories, shame about the practice. Marx did many things. But inventing class was not one of them.

If you look at the other people around at the time - Charles Clarke, Alistair Darling, Jack Straw - they've all gone. And they're not old. What's happened is that someone who is quite old - Jeremy Corbyn - is now leader. We have to take some responsibility for that.

I feel like thanking Paul Dacre every time, because the reason they ask me is because they think I've come through the other end with a pretty good reputation. Loads of people get a bad press but have a good reputation. [David] Beckham - think what he went through. [Bill] Clinton, likewise. You just have to be true to yourself.

In an ideal world, it would not take a film star to get the media focused on mental illness.

I do think it's strange that I get associated with Iraq more than the people who were Foreign Secretary or Defence Secretary. It's because of my closeness to Tony [Blair], which I don't regret at all. I think that was a privilege.
