I think UK is heading to a general election as well. I don't think it will be as soon as October but I think it could be announced as soon as October. I am guessing Boris will wait until he can confirm the EU will 100% not budge.
I agree that he will blame the EU and probably parliament as well for the 'no deal Brexit' scenario. I doubt that will be enough for the Conservatives to win an election. I don't think they will form a coalition with the Brexit party. I think the alternative coalition of Labour, LDP, and Greens would win. I think this alliance will result in another referendum. I think this time remain will win but it would be hilarious if Brexit won again.
I still support Brexit for the same reasons as always but I also believe the misinformation spread during the campaigning had a big part to play for Brexit winning the first time around.
