Don’t know where you got your information from, but if it was one of the Mail, Express, Telegraph or Sun, I would suggest that you find a more reliable and truthful source.
Your comment “the recent behaviour of the EU in respect to interrupting private industry supply chains“.
The UK voted to become a third country, which meant that supplies into the EU and from the EU would be subjected to different rules, rules that the UK helped to create whilst a member of the EU.
The EU has actually allowed us time to try and get our act together, rather than impose the rules as hard as they could do, so blaming them for this clusterfuck is completely wrong.
All the damage done to private industry has been done by the UK government, and more importantly by the Tory party who decided to come out of the single market and the customs union, thus inflicting those damaging rules on private industry and it could get worse before it gets better. But not because of the EU.
If you voted Leave then put your hands up and acknowledge that you had something to do with the mess we are in, because of Brexit, instead of blaming someone else.
