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.

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.

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

We need a new British business bank with a clean balance sheet and an ability to expand lending rapidly to the manufacturers, exporters and high-growth companies that power our economy. Today I can announce we will have one.

On banks, I make no apology for attacking spivs and gamblers who did more harm to the British economy than Bob Crow could achieve in his wildest Trotskyite fantasies, while paying themselves outrageous bonuses underwritten by the taxpayer. There is much public anger about banks and it is well deserved.

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 am going to confront the old-fashioned negative thinking which says that all government needs to do to generate growth is cut worker and environmental protections, cut taxes on the rich and stroke 'fat cats' until they purr with pleasure. I'm completely repudiating the idea that government has to get out of the way.
