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?

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

I'm afraid that's in the nature of modern politics - it's as much conducted by abuse as argument.

As the world transforms, moves closer together, jobs are displaced, and the world of work completely changes the way we live, the way we think. As that revolution goes on around us, it is going to pose political challenges of which immigration is one very obvious one, which are going to be extremely difficult to deal with. But it's like free trade. You know, in the end, if we go protectionist, we'll make a mistake.

People divide into groups where they talk to each other, but don't talk across the divide. And yet most of the challenges we face in the world today are challenges that are to do with trade, with technology, with how you make sure that people are properly educated, reform your health care system.

When I started out as Prime Minister I wanted to please all the people all the time. By the end I was wondering if I pleased any of the people any of the time.

Whatever the dangers of the action we take, the dangers of inaction are far, far greater.
