You can't win with some people. If you're not in government, you're criticised for being not serious. If you are in government, you're criticised for wanting power. That's the Labour party's line of attack, and it's a bit ridiculous.

Banks operate like a man who either wears his trousers round his chest, stifling breathing, as now, or round his ankles, exposing his assets. We want their trousers tied round their middle: steady lending growth; particularly to productive British business, especially small scale enterprise.

When my job was attempting to predict future economic developments for the Shell oil company, I was frequently reminded of an Arabic saying: 'Those who claim to foresee the future are lying, even if by chance they are later proved right.'

Investment banking has, in recent years, resembled a casino, and the massive scale of gambling losses has dragged down traditional activities as banks try to rebuild their balance sheets.

Well, as I said, you know the issue of Greek debt, they've grasped the principle of debt reduction. I think most people would argue that probably more needs to be done on that front, and they've just begun to take the first steps to accepting that there's going to have to be much closer economic integration in Europe.

I clearly believe a lot more than some of my coalition colleagues - Tories - in redistribution and using the tax system for that purpose. I also believe in the government having an active role in the economy, which is having an industrial strategy. I'm not a believer in laissez-faire.

In my job I meet many outstanding, world class, British based companies. But we need more companies and more jobs in the companies we have.
