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.

I don't feel comfortable with luxury, and I try to stay fairly normal.

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.

The economy has become seriously unbalanced. Its growth has not been driven by investment or by overcoming Britain's long-standing weaknesses in investment and productivity, particularly skills. Instead, there has been a binge of debt-financed consumer spending.

The government increasingly resembles somebody who is trying to give the kiss of life to a corpse.

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 think what is happening is I think first of all there is confidence in the U.K. economy. We're in a German rather than a Greek position in international financial markets, which is very positive and keeps our debt service costs down, and we're also beginning to see real evidence of rebalancing.
