The worrying thing now is that whatever decision is made by Johnson on a trade agreement, it isn't going to be based on the best possible long term outcome for the future of the country and its people. It will be a purely political decision based on what will play out best for him personally.
Can he sell the a dressed up version of the same deal, that has been on the table all along and could have been done months ago, as being the outcome of his world-beating negotiation ? Or does he calculate that the response from the nut-job, Brexit means Brexit, tory gammon faction (including Farage and followers) will cause him more political long-term harm ? Which outcome will present the best sound bite opportunity for a "Churchillian" victory speech that he will want to see as his defining legacy.
He only backed Brexit in the first place because that looked the better option for his personal political ambitions, so he ain't going to change now. The camouflage and distraction that Covid gives him in terms of the hit on the economy may be a temptation to go full Union Jack, Rule Britannia, Free Haddock for Everyone, sign up to be a deck-hand on a trawler........
My guess is that he will do a deal and smear lipstick all over that pig......probably leaving (hiding) some of the finer, more contentious detail to be agreed ("with our friends, allies and partners") over time. The bloke is a wretch.
