It’s so bloody stupid. Take that example of pharma and biotech.
The UK cannot seriously deregulate a lot of it’s requirements for pharma for two reasons 1) it’s spent years building its reputation as a world leader on quality and research 2) on its doorstep are very similar economies with basically the same standards.
Brexit is a joke. We can put our standards in, it becomes a further cost to business who don’t want to spend more money complying with new standards. They end up relocating elsewhere. I sometimes think it was solely voted for by people who didn’t realise Britain was so integrated - it wasn’t like it would be easy.
