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?'

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.

Tony [Blair] slowly sucked me back in for the 2005 campaign, and from six months out, I was basically working full time trying to keep the Tony[Blair] - Gordon[Brown] thing together for the campaign. It was awful.

Paul Keating told us before we were elected that you can do deals with [Rupert] Murdoch without saying you were doing a deal. Did we do that kind of thing? Maybe. But from around about the turn of the century, I felt strongly that we had to do something about media ownership and self-regulation. Tony [Blair] disagreed.

I hold no candle for George Osborne whatsoever. He has no strategic skills, is a hopeless chancellor, has no idea how most people have to live and his policies are failing and hurting millions.

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

Like most meaningful activities, campaigns are team games.
