Really important to keep in mind how utterly disastrous <230 seats is for Labour and that massive, massive decisions will need to be made in the next weeks if that's how it turns out. If the Michael Foot 1983 vote is no longer the 'floor' (labour getting less that 209) - well, Labour didn't get back into power for 14 years after that. That's potentially 20 years of Tory rule if replicated.
It's going to be very, very rough.
..it's what I expected when the election was announced. I fear Corbyn will go and be replaced by another, younger Corbynist. It could actually have been worst if Corbyn did better than expected. If the poll is true, I expect the next election in 5 years time to be the earliest that a much needed root and branch change will take place in the party's governance, particularly how they elect their leader.
The alternative is that a breakaway party will be formed away from the Momentum influence. Saying that, the poll might be wrong.
