I feel like everyone else in this country today. I am utterly devastated.

For me, 9/11 was a game changer. It altered my perception of the security threat we faced. I took the position that Britain should be shoulder to shoulder with the U.S. It was a big decision; I didn't take it lightly, or in ignorance of its consequences. It's a big commitment for a country to give, but I believed it was the right thing to do.

There is no way you're going to have an event like 9/11 and expect things to remain the same. They killed 3,000 people in New York on that day, and if they could have they would've killed 300,000.

I think it's important for people like me to evaluate and reevaluate.

It is absurd to say in respect of any intelligence that it is infallible, but if you ask me what I believe, I believe the intelligence was correct, and I think in the end we will have an explanation.

Personally, I have already turned down the Downing St thermostat by 1 degree

I've never ruled out the possibility of going back into public service.
