I'm sure they'll be laying the blame for any fall out on the EU. No doubt with the tabloids in support, the masses will lap it up.
As you mention, people think it's done and dusted now. The only outcome that will not lead to an absolute cluster [Poor language removed] trade deal wise is if we go with full alignment with the EU on standards for goods and services. There's no way things can be picked apart without producing an absolute avalanche of red tape, putting firms out of business as a result. I got a bit obsessed reading up on all things brexit, but since the election I've pretty much given up. The whole thing contains countless paradoxes...
For example the Irish border. It'll become clear as day that Johnson has told the population a pack of lies regarding goods moving between GB and NI. This whole 'throw the documents in the bin' line is reckless. The EU are committed to protecting standards and will not allow goods to move via this route if correct checks are not being carried out. All GB serving businesses in NI are likely to struggle as they will have to account for not just individual items that are sold, but the constituent parts of them as well. This will make NI businesses uncompetitive in the long run. In the same respect, the EU will be wary of goods coming into the EU, via NI, via GB if GB standards undercut EU, giving GB firms an unfair advantage. That's before you even get into the breakdown of when you are trading goods and services in one product, or even more obstructive, the rules around country of origin.
Recession is unavoidable IMO. I've decided to give up reading about it though, as the whole thing is so frustrating. Even reading this thread has annoyed me.
