I cannot think of any circumstances in which a government can go to war without the support of parliament.

I have absolutely no doubt at all that we will find evidence of weapons of mass destruction programmes.

In Downing Street they called me 'Boss'. Civil servants would always call me 'Prime Minister'.

The Donald Trump phenomenon in the U.S. is mirrored completely by the Brexit phenomenon in the U.K. It's very similar forces. And what is interesting to me is there are two different groups that come together, who don't really agree with each other, but have come together in unity against, if you like, what is perceived as the status quo, or - and certainly what is a more center-right or center-left type of politics.

In government you carry each hope; each disillusion. And in politics it's always about the next challenge.

Do I know I'm right? Judgements aren't the same as facts. Instinct is not science. I'm like any other human being as fallible and as capable of being wrong. I only know what I believe.

I also, as I think most people do, have a healthy instinct that if we upset the balance of nature, we are in all probability going to suffer a reaction. With world growth, and population as it is, this reaction must increase.
