After the Berlin Wall came down I visited that city and I will never forget it. The abandoned checkpoints. The sense of excitement about the future. The knowledge that a great continent was coming together. Healing those wounds of our history is the central story of the European Union.

Britain is characterized not just by its independence but, above all, by its openness.

There is a growing frustration that the EU is seen as something that is done to people rather than acting on their behalf. And this is being intensified by the very solutions required to resolve the economic problems.

Now I know which came first - the chicken not the egg.

If we are going to try to get across to the poorest people in the world that we care about their plight and we want them to join one world with the rest of us, we have got to make promises and keep promises.

We're all agreed that climate change is one of the greatest and most daunting challenges of our age. We have a moral imperative to act and act now.

The biggest danger to the European Union comes not from those who advocate change, but from those who denounce new thinking as heresy. In its long history, Europe has experience [with] heretics who turned out to have a point.
