Bingo. He expects there will be some short-term chaos after a no-deal Brexit (shortages of food and medicine, maybe even resumption of sectarian violence in Ireland) and that the public will blame Johnson.
I hope he's wrong, but that's his strategy.
Corbyn is and always will be a bluidy communist.
He wants Brexit and he wants no deal Brexit.
The chaos that will cause will help him bring his commie “paradise “. No wonder the communist party of the UK supports Brexit
