Johnson's and the ERG Group's only goal is a no deal Brexit... 11 months are not enough to have a proper agreement. Johnson is against a prorogation, so it will be no deal. This is why the ERG Group has been so quiet. Johnson must have promised them something. Also, prepare for a unified Ireland and the collapse of the United Kingdom when Scotland leaves...
But, it is at the difficult bit. We have removed our leadership and influence, but that is a limited achievement to far. The downsides to that are more vague.
Now it gets tricky. It seems that no determined leaver will express an opinion on which of the three to drop:
- Leave the SM and customs union
- Preserve the Good Friday Agreement and so maintain peace and international relations
- Preserve Northern Ireland as intergral to the UK
This makes sense, as it will involve taking responsibility. It also involves accepting that not all the 17.4 million who vote Leave wanted the same thing.
For the ERG, it is vital that tax evasion and closetted accounting be permitted far more than it would in the EU and a drop in the standard of living for people in the UK and the threat to the union is a small price to pay for that. But, there will be many Leave supporters who will disagree.
We are at the point when everyone is broadly happy. The only loss is that the people of the UK will not be able to vote for the people to the EU who will make decisions and the British Government have less influence. But, that is a price that almost all Leavers are happy to pay, as @Diana7
What when the price goes up?
And, if the ERG are behaving because of a promise that Johnson has made them, then they are far stupider than I really believe they are.
