I am a great believer in the law of unintended consequences. I saw that in the financial crisiswere people wanted to do things, and i could see the problem that would result if we were to do that. The big challenge for policy in the next decade is going to be to try to reconcile quite large shifts in the structure of our economy with the wish to maintain inflation at a low and stable level. And this idea that a prime minister should come out and talk in rather flippant terms about by two thousand and 50, we'll all be driving around electrical vehicles as if nothing will happen was a big mistake.
