Change is a process: future is a destination. People want a sense of hope, possibility and pride about Britain.

In an era of billion-person countries and trillion-pound economies, we need to find ways to amplify our voice. We are most likely to be heard when the Chinese negotiate with a £10 trillion E.U., not a £1.5 trillion Britain.

The Government have consistently made it clear that the mechanism in the United Kingdom whereby the European draft constitutional treaty could be implemented is approval by the House of Commons followed by a referendum of the people of Britain. There is no question of implementing it by the back door.
