Labour won’t go into coalition with Corbyn so as long as he stays it’s a coalition with the Tories,
Do you just make this up? Everybody says they won't go into a coalition before an election, not just labour. Corbyn already proposed a coalition to form a gnu.
I think today’s Supreme Court judgement will say Johnson was and is allowed to prorogue parliament, but there should be a time limit.
I also think this doesn’t really matter as he’s going to have to apply for an extension on the 19th and then resign.
Labour won’t go into coalition with Corbyn so as long as he stays it’s a coalition with the Tories, who I think will get ~280 seats.
