The breaking of an international treaty by the internal Market bill is all part of some Cumming brinkmanship gameplay.
We aren't dealing with adult politics here, it's just playing to the gallery.
Its not clear what the true objective is
It is:
an obvious dead cat.....its filling newspaper acreage with people getting all hot under the collar, that would I guess be a smokescreen for what is really going on.
It's either so remainers and EU will get cross, then that gives Boris a chance to ramp up the blame game.
I bet Boris hoped Starmer would start stamping his feet, which would have given Boris a big opportunity to play Starmer against the "will of the people"......so Starmers removed that game play rather well.
Or it's a rather puerile attempt to get EU to agree a deal
Or it's an opportunity to push through a no deal and blame it on remainers trying to thwart UK sovereignty.
Who knows, ultimately Boris is furked and he is throwing any Shiite at the wall hoping some will stick.
Bring on no deal and food shortages.
