Now the main areas of higher education that still enjoy considerable financial support from government are subjects like engineering and science and the research ringfence which is the basic minimum to protect Britain's scientific competitiveness.

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.

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've always been comfortable working with women and I've had two happy marriages. Draw what conclusions you like from that.

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.

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.

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