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 real problem at the moment is that the banks - because of their existing culture, which is frankly anti-business, obsession with short-term trading profits, not focusing on the long term - are throttling the recovery of British industry.

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.

I have managed to infuriate the bank bosses; acquire a fatwa from the revolutionary guards of the trades union movement; frighten the 'Daily Telegraph' with a progressive graduate payment; and upset very rich people who are trying to dodge British taxes. I must be doing something right.

I'm now happily remarried to a good cook, which encourages me to be lazy. I like to think that I'm a new man, but perhaps I'm not. I offset it by doing the ironing, though. She has a small farm in the New Forest with a herd of cattle, so she serves up a steak and kidney pie made with her own beef.

These 'masters of the universe' must be tamed in the interests of the ordinary families whose jobs and livelihoods are being put at risk. The Tories won't say anything about the current crisis as they are completely in the pockets of the hedge funds.

My time at Shell was a most valuable experience because it taught me to look at the world in a long-term way. Shell takes a 20-year view on events and plans for different scenarios. It makes you see the world as a kind of large matrix.
