If Boris is "successful" I'm convinced we will end up out with some form of freedom of movement.
1) That isn't a sticking point in parliament not even with the ERG. They need that for their Utopian society.
2) Not many MPs are going to out themselves as anti-immigration.
3) Boris is very pro freedom of movement. In fact it's the only consistent political position he has taken.
Yes, I'm beginning to think that as well.
He's very insistent on being out of the EU by 31/10. He knows he can't get 'no deal' through the house so he has two options: another GE (which is very, very risky) or a revised deal. The EU aren't really going to play ball unless he moves one of May's red lines. I suspect he will either put the border in the Irish Sea, keeping NI in the CU or sign up for some form of FoM - or even stay in the EEA.
I can't see any other options for him
