Mrs Cameron keeps a rather better weekend diary than I do.

Government has the power to help improve well-being

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.

I want completing the single market to be our driving mission. I want us to be at the forefront of transformative trade deals with the US, Japan and India as part of the drive towards global free trade. And I want us to be pushing to exempt Europe's smallest entrepreneurial companies from more EU directives.

Countries are different. They make different choices. We cannot harmonise everything. For example, it is neither right nor necessary to claim that the integrity of the single market, or full membership of the European Union requires the working hours of British hospital doctors to be set in Brussels irrespective of the views of British parliamentarians and practitioners.

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.

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.
