I'm getting a feeling that May is realising that she is toast. Think this "deal"
will not pass, not in HoC, and probably not in cabinet as well. My expectations are currently shifting fast towards snap elections.
They explained some details of it on main news his evening. The Brits would have lost all their marbles if accepting this. As a German commentator put it 20 minutes ago in the Tagesschau: "The EU left the British with only this choice: either a future very close to the EU, or an exit with chaos." And as I said from all beginning on: this was always all the EU ever was about. No mutual success, but either EU domination: or punishment of the UK. You do not turn your back on the wonderful EU without getting retaliated against, for revenge. Hurt narcissism and all that. Roots very deep in human psyche.
From a British point of view as I would define it, this "deal"
is absolutely unacceptable.
Finally, time to let go all illusions. This was forseeable.
