Michael Gove:
In plain English: "We had our fingers crossed behind our backs, the agreement means nothing, it was just something we had to say to get the EU to move on to trade talks. It isn't worth the paper it is written on."The British people will be in control. If the British people dislike the agreement that we have negotiated with the EU, the agreement will allow a future government to diverge. After a transition period, the UK will have full freedom to diverge from EU law on the single market and customs union�.
And to be fair, the EU's dictated sequencing of talks was always stupid, because if there's a caveat "nothing is agreed until everything is agreed" then the sequence is actually irrelevant.
"Senior EU official":
In plain English: "we are the bullyboys here, you are supposed to have no power. But you have been negotiating with a gun pointed at your head by brexiteers in your own cabinet, and using your own weakness to leverage concessions from us, by threatening that if we don't then we'll end up talking to Johnson, Gove or Rees-Mogg instead of you (oh shit!). This is intolerable. We only negotiate when we hold all the cards. Therefore even though we just agreed to move on to trade talks, there will be no actual trade talks until you've got your cabinet united behind you and can no longer threaten us with the disorderly hard brexit the Germans are terrified of."member states could be ready by February or March to have substantive talks but only if May had got to grips with her cabinet and agreed a settled position.
Which is, of course, completely impossible this side of another general election which returns a decent tory majority.
