As I write (1030z Saturday) the head of the UK and EU are going to speak on the 'phone and as yet there is no BREXIT trade deal, even though to have one is in everyone's interest.
I suspect there is brinkmanship on both sides. In these last few weeks, I think these children should throw away their toys and behave as grown-ups if this is possible. We all know that is what is best.
Go on, get a mutually good deal that all can sell as a success.
UPDATE 1848z: Talks to continue on Sunday.
