There was, of course, a global financial crisis. But our Labour predecessors left Britain exceptionally vulnerable and damaged: more personal debt than any other major economy; a dangerously inflated property bubble; and a bloated banking sector behaving as masters, not the servants of the people.

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.

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.

No, and in fact I get a bit frustrated, because I'm actually quite good at one-liners, and I've had hundreds of them over the years, and they sink without trace, and I get very frustrated.
