By asking the question 'Am I happy?,' and via the answer setting out what I mean by happiness, there is a political route that can be taken, by asking another question - 'Can politics deliver happiness, and should it try?'

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.

Clinton is a big personality who has led a big life, and for some of the media conventional wisdom to boil it down to a view that 'all people are really interested in' are a few moments of madness in the Oval Office gets him, the importance of the presidency, and the significance of his life, all wrong.

The thing about politicians in Britain is that they are out there, you can lobby them, get close to them, there are loads of ways you can protest against them, and booing is a pretty weak way of doing it.

May I share with you my earliest memory of a political row? It was with my mother, about the Queen - classic Freudian stuff, shrinks would say. I was eight, and refusing to watch the Queen's Christmas Day broadcast.

For all that the papers would say I was a liar, I took the words I was saying at briefings as seriously as Tony Blair took what he would say at the Despatch Box. I find it very difficult not to tell the truth. I felt I was accountable for what I said.

The media are obsessed with spin doctors and with portraying them as a bad thing, yet seem addicted to our medicine.
