Well obviously it was a failure and always was going to be a failure. Whereas before there was frictionless trade, travel, employment, living, there is now an ever expanding wall of bullshit and red tape. Getting goods to and from Europe is subject to import duties and delays that just kills trade - why would a Spanish company buy widgets from the UK when a supplier in Germany can supply them faster and reliably without any customs redtape?
It will take the UK years to form other trade deals, none of which will be remotely as favourable as they would get with negotiating power of the entire EU behind them. There have already been noises in the UK press about having to take food from the US which would fail EU standards - bleached chicken, GM crops, growth hormones etc. And that’s because when the US comes to the negotiating table they’re going to bend the UK over and screw them. And China, India and the rest of the world will be lining up for some sloppy seconds.
He’s really gunning for that Hero of Russia medal
