Slightly off topic, but I wonder what would happen if May just notified the EU of our triggering of A50 anyway. Yes, the Supreme Court ruled it needs an act of parliament but since A50 has no take-backsies, what could they do? Presumably the EU would interpret the head of the UKs executive saying "Yo, we're triggering" as triggering, even if they know the British supreme court had ruled it needs an act - that is an internal issue in the UK.
I'm not saying she will or should do this btw, I'm just curious.
Can the house of Lords put forward a vote of no confidence in the government? I dont know
