I think the very first thing to say is that when we came to do the annual review debate, we were in possession then of the Half Year Economic and Fiscal Update. And when we took the time to compare that to where the Treasury thought we would be when they produced the pre-election fiscal update, only a matter of three or four months beforehand, the differences were already stark. And that goes to illustrate the point that we are living through an environment of uncertainty and volatility at the moment.
