Blue Valkyrie
Not seen such Bravery!
1 - 6 Probably, but then anything could happen.This is how I see this going:
1. EU Summit rejects Boris's backstop solution. No "Deal" reached.
2. 19 Oct 19 - Parliament reconvenes. Johnson asks for vote on his backstop solution to give it parliamentary backing. Corbyn rejects this as EU has already rejected it. Corbyn demands the Benn Act be executed and Boris seeks extension.
3. Boris leaves it as late as possible but eventually caves and writes letter seeking extension.
4. Boris immediately announces a General Election for the end of November.
5. Boris goes into full "Me and the People vs Parliament" mode.
6. EU accept extension to January.
7. EU also announce they'll extend further to June if UK wishes to hold a Second Referendum.
8. Farage kicks off that No Deal hasn't happened, that Boris is full of shit and an electoral pact is off.
9. Boris takes a kicking in the polls as Leavers begin to desert Tories for Brexit Party.
10.General Election produces another hung Parliament.
Hopefully the DUP lose influence, and the tail stops wagging the dog, after an election though.
