Oh, don't worry, the UK government certainly *will* do that- and try to sell it as a victory regardless- once it realises it's not in the powerful position to dictate terms to all and sundry as was promised by Brexiteers and that the US has it over a barrel when it comes to a trade deal. (#) Especially since their short-sighted non-planning didn't take into account a bullying shitstain like Trump getting into power there and actively railing against the WTO they put so much faith in.
(#) Funny, it's almost as if it benefits the US to be dealing unilaterally with a much smaller and weaker partner. Particularly one that's desparate for a trade deal thanks to its own delusion that it was still 1951 and it could still do what it wants like Suez never happened.
