This may sound arrogant, but I believe that if we'd done teamship better, we'd still be there. Where we fell down was the inability to hold together. We should have learnt from the great football teams. The players may not like each other. They have egos, they have their own ambitions, they have different personalities, but they are still bloody good teams.

Don't accept that you are in crisis just because everyone says you are.

My aunty says I'm the double of my father. He was a workaholic, which I've definitely inherited. And like me, he could be the life and soul of the party, but also quite withdrawn.

So here is one of my theories on happiness: we cannot know if we have lived a truly happy life until the very end. This view of life and death was reinforced by my close witnessing of the buildup to the death of Philip Gould. Philip was without doubt my closest friend in politics. When he died, I felt like I had lost a limb.

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.

I never met David Kelly, but I knew from what he told other people that this was not his view. The BBC were saying that Tony Blair was making up lies so that he could send young men and women to war, maybe to die. I think that if the BBC had done their jobs professionally, they'd have realised that you couldn't justify what they said. And nothing has emerged since to justify that report.

To me, marriage is partly a religious thing and I'm not religious.
