The French must be quaking in their boots at the idea of that lady from Kent saying she will boycott French products...
Goes both ways, and the EU can buy from each other and basically cover all their needs this way, and also exports ot most of the world, including USA.
Which product would the EU 27 need to buy from the UK, which they can't get from each other. Stilton and whisky - perhaps. I'd miss both, but certainly could live without.
Irish whiskey is not bad at all, and there are plenty of great blue cheeses in Europe (but yes, I'd miss my favourite, Stilton- but hey ho).
