Because I happen to believe that the best policy solutions lie in the center ground, then I want to see, how does the center revitalize itself? How does it develop the policy agenda for the future? And how do we link up people who have the same basic ideas and attachments to the same basic values across the world?

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.

Now, again, what the center ground has got to do is to respond to people's genuine concerns and fears.

Bill Clinton has been a true leader of the western world. He has been a friend and a counsel to me and other leaders right around the world.

Well, we definitely need a strong and clear and assertive America. That's for sure. But you've always got to build alliances. And so it's very important that we are able to build those alliances. And where we don't do what in a way to extremists want us to do, which is to make this into a battle between the West and Islam - it's not. This isn't a clash between civilizations. It's about whether the values of tolerance and respect for difference prevail.

I think crime is a huge issue for people. If you were living in the poorest state, and you've got drug dealers at the end of the street, and your life's in misery, and you're afraid of your kids going out the door. I mean, the job of progressive politicians is to do something about that.

What we want to see is the development of human rights and greater democracy, not just because it is our system but because we think that's the best way that economic and political development go hand in hand.
