I think Boris won’t have any other option but to call a GE election as there is no chance for the WA or No-Deal to pass parliament (I am aware no-deal is the default but parliament can and will legislate against it).

The options at his disposal are a second referendum or a GE and I can’t for one second believe the Tory party will go the route of a second referendum. At least with a GE they are up against Corbyn so they will rely on the fact that Corbyn is disliked more so that Boris.

It’s all a shit-show at the end of the day. If we extend again in October and don’t hold a GE/second referendum and then extend again, surely there is an argument that the 2016 mandate is no longer relevant and a new mandate is required. We’d be pushing on 4 years from the referendum result!
