I believe something very deeply. That Britain's national interest is best served in a flexible, adaptable and open European Union and that such a European Union is best with Britain in it.

The prime minister says he has a vision for change, well put that to the people of the country.

Just as I believe that Britain should want to remain in the EU so the EU should want us to stay.

I want to be the voice of change and hope. I want to confront the big challenges this country faces.

Because with courage and conviction I believe we can deliver a more flexible, adaptable and open European Union in which the interests and ambitions of all its members can be met.

We can't afford to waste time going slow on changing our party so now is not the time to put our foot on the brake. Now is the time to press on the accelerator.

Cap the well, yes, clear up the mess, yes, make compensation, yes absolutely. But would it be right to have legislation that independently targets BP rather than other companies? I don't think that would be right.
