The civil service, the rest of the establishment, some of the cabinet, the media, and most of the opposition have deliberately created a situation where the EU know that a full proper Brexit is going to be a really tough thing to deliver in the UK.
This combined with Mrs weak & wobbly behaving like a scared mouse, has greatly strengthened the EU hand against the UK.
They know that they have a strong hand, politically because of this and are determine to give us a deal which in other circumstances would be ludicrous.
When David Davis obviously became completely sidelined from doing the job his department was created for, and his job effectively taken by Olly Robins - a hardcore europhile who is a mere civil servant, they knew that they were going to be offered something by Theresa which is a very watered down Brexit.
They will now feel confident enough to negotiate watering it down even more, to the point where its meaningless. Brino in other words.
Its crunch time now. Either she has to go and be replaced by someone stronger and more competent, or our democracy is dead.
