I have a nightmare about Tony [Blair] and Gordon [Brown] killing each other. Not every month, but now and then. I also have a recurring dream about losing.

All of this is happening because there has still been no reckoning post the financial crisis. So governments have fallen, one bloke has been to prison, the banks have gone pretty well back to status quo, the rich are getting richer, and the poor are getting poorer. And it's fuelling anger. And somehow [Donald] Trump, who represents the worst aspects of capitalism, has persuaded people he can deal with that.

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.

My public caricature - that of a self-confident alpha male - is only partly accurate.

I remember talking to Alex Ferguson about Tony [Blair] and Gordon [Brown], and he said: "Why doesn't Tony just get rid of him?" But if you sack someone in football, they can't turn up to training the next day. In politics they're still on the pitch. Gordon would still have been a big player.

There is something in me that makes me see things through.

One in four of us will have a mental illness at some point. That is a lot of people.
