Britain is no longer one of the world's price setters. It is painful. It is a challenge to us in government to explain all that, and it is a pity that the political class is not preparing the public for it to understand how massive the problem is.

My college, Fitzwilliam, was pretty good but unfashionable and I lived in digs so I was not part of the cloistered 'old college' environment, which frankly was a bit intimidating. But I worked hard and settled in by exploring politics and girls.

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.

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.

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.

My job is to support businesses, that means promoting British commerce in the big emerging markets that have been neglected in the past. It means keeping Britain open to inward investors, trade and skilled workers. It means cutting red tape which is suffocating growing companies which create jobs.

The degree of leverage now being reversed is on a staggering scale, and the underlying global imbalances – notably between the savers and the spenders – will require long and painful adjustment.
