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.

Because I'm a democrat! The will of the people is sovereign.

I want the European Union to be a success. And I want a relationship between Britain and the EU that keeps us in it.

All those countries who keep their aid promises should be proud of what they've done

But we will say something else. That for far too long in this country, people who can work, people who are able to work, and people who choose not to work: you cannot go on claiming welfare like you are now.

We are a great country, and whatever choice we make we will still be great. But I believe the choice is between being an even greater Britain inside a reformed EU or a great leap into the unknown.

I believe man-made climate change is one of the most serious threats that this country and this world face.
