One day, we will look back and wonder how on earth we used to believe that depression was a lifestyle choice, only to be debated and taken seriously when an A List film star took his life, and the world filled with people saying how shocked and saddened they were.

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.

There are many reasons for the decline in royal esteem. One is that so many of the royals are thick.

My closest friend, who died not long ago, is buried near Marx's grave in Highgate cemetery, so I see the gaggle of admirers laying roses at the foot of his tombstone regularly. I have never been tempted to leave flowers there myself. Great theories, shame about the practice. Marx did many things. But inventing class was not one of them.

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.

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

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.
