One of the brexit ministers (can't remember his name) said as he resigned that he had not had any input in the decision making nor discussions whilst in post. David Davis also said he hadn't even seen the Checkers proposal until it was unveiled and that was why he resigned.
That makes it a mockery to employ Brexit believing ministers in that post if they are not allowed to be part of the discussions.
All IMO
Don't you wonder why there have been so many ministers resign? I don't.
Hmm. How could he not have seen the Chequers plan if he was in charge of UK negotiations?
IMO, they all had different ideas of what Brexit meant, didn't have a clue how complex it was going to be, and believe(d) that the UK was going to be able to dictate all the terms.
It took ages for it to even sink in that the divorce agreement and trade deals were different phases...
A bit like Flat-Earthers going on a world conference cruise and never stopping to wonder how ships actually navigate.
