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.

I know it sounds trite but I wanted to make a difference. Political debates with my father had been fraught because he was uncompromising and explosive but if he taught me one thing it was to air my views.

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.

Banks operate like a man who either wears his trousers round his chest, stifling breathing, as now, or round his ankles, exposing his assets. We want their trousers tied round their middle: steady lending growth; particularly to productive British business, especially small scale enterprise.

Where there is flagrant abuse of corporate entities we must and will seek to tackle it.

Regulators are a backstop: they don't own banks. The governance at the top of our leading banks has been shown to be lamentably weak. No one at the top of Barclays will take responsibility for systemic abuse.
