Fuck him. I want it dragged out so he suffers and is shamed as much as possible, though I don’t think he is able to feel shame.
Reality is he’ll get another highly paid job, celebrate himself as the man who ‘got Brexit done’ and continue to live in luxury, not giving a shit about the lives he’s destroyed
Political parties have no real constitutional existence in the Westminster system. They evolved from not much more than groups of friends at Parliament, where whomever had the most support would be asked first to form a government that could hold the confidence of the House. Parties are really just a short hand for that process. So, they could rescind their resignations from the Conservative Party without consequence beyond the Conservative Party.
Hard to see how that ends short of either an own goal confidence motion, or the sort of intervention that the Queen has spent one of the longest reigns in history trying to avoid at all costs.
