Competitiveness demands flexibility, choice and openness - or Europe will fetch up in a no-man's land between the rising economies of Asia and market-driven North America.

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 next Prime Minister walking through that door will be me or Labour Party leader Ed Miliband, you can choose an economy that grows, that creates jobs, that generates the money to ensure a properly funded and improving National Health Service ... and a government that will cut taxes for 30 million hard-working people ... or you can choose the economic chaos of Ed Miliband's Britain.

Let me completely condemn these sickening scenes; scenes of looting, scenes of vandalism, scenes of thieving, scenes of people attacking police, of people even attacking firefighters. This is criminality pure and simple and it has to be confronted.

I know the British people and they are not passengers - they are drivers.

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.

No treaty should be ratified without consulting the British people in a referendum.
