The forecasts are taken from the OBR and if the hon. Gentleman looks at its rather thicker report, he will see its comments in relation to Brexit and trade deals. The OBR is still rather negative on trade deals and I think that it is wrong. I have the greatest respect for the OBR, because it is the one body that during the Brexit campaign behaved properly and within its remit and did not dabble its fingers into the politics of the Brexit debate. Its view is cautious on trade. It thinks that over the next 10 years, post-Brexit, our trade position will be less good. I happen to think that that is wrong.
