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

You choose your own reality and you - social media then amplifies those conspiracy theories. So that's why I say social media is itself a revolutionary phenomenon.

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.

You don't have to keep looking at the future foreign policy in terms, simply, of the past.

There are people who are anxious about immigration for reasons that are perfectly sensible. They think it's uncontrolled. They think it's, therefore, arbitrary in its consequences, and there are some communities affected much more deeply than others.

Ask me my three main priorities for government, and I tell you: education, education and education.

If you don't see the Internet as an opportunity, it will become a threat. In two or three year's time, the Internet will become as commonplace in the office as the telephone.
