The so-called Yellowhammer report is wrong. I can say that with absolute confidence. Every forecast is, and I’ve delivered a lot in my time, always with that caveat attached to them. But in my opinion that does not mean it is not important. That’s precisely its significance.
All it really says with certainty is four things. The first is that we do not know what will happen if we hard-Brexit.
Err, that’s what the report is telling us. What will happen.
