We should confine booing in sports arenas to sport. I love a good boo as much as the next football fan.

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?'

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.

Tony's [Blair] convinced I'm going to find God. I do have spiritual moments, but I don't think it's God.

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

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

Friends have suggested that I am the least qualified person to talk about happiness, because I am often down, and sometimes profoundly depressed. But I think that's where my qualification comes from. Because to know happiness, it helps to know unhappiness.
