If.
As it stands, here's what I am predicting will happen. (I am not delighted by this prospect by any means, by the way, I am a remainer.)
Once the no-deal bill has finally passed, Johnson will once again call for a GE and Corybn will feel unable to refuse it. The objection that we cannot have an election until the threat of a no deal Brexit is removed, is no longer valid. Resisting further, will only damage Labour's standing further and diminish any chance of victory in an inevitable election in November or soon after. So he will agree, and we WILL have an mid-October GE.
Boris and Farage will do a deal of some kind and whilst that will lose a lot of moderate remain-inclined Tory voters, those losses will be more than compensated for by the joining of the two forces. Whilst on the other side of the fence, the Remain vote will be destructively impaired by being split between Labour and the LibDems.
The net upshot is that Boris will gain a slim majority, my guess around 20, but embolded by the election win and with the extra seats, he will repeal he no-deal bill and we will leave on October 31st. Whether the EU will throw us a last bone which enables that to be with some kind of deal, or not, we'll see. Probably not because it will be too late.
You may laugh at this. Many probably will. But let's just see.
