Boris loses vote. You lot are really in the s**t now aren't you? All hail King Jerry. You poor sods.

It was a vote that asked "should", it's not passed as law or as a bill..
To actually stop a no deal Brexit, it has to be changed by EU law.
If an acceptable deal, by the UK, is not reached with the EU, then the agreement says the member Country wanting to leave can leave the EU without a deal. Acceptable trade deals can also be agreed too after Brexit between the EU and the UK.......
Boris will win a General Election, Corbyn knows it, he knows he doesn't have the support of the majority of people to win. A GE would be devastating to the Labour party, and Labour MP's know it.
Many remainers have changed their stance and gone over to the leave side, and as Ristac pointed out, there are quite a few million oldies who go along quietly, then cast their vote for Brexit.
Tory and Brexit combination will be a shoe in for Boris, Labour know that too.
Basically what you'll have is, most Tories, UKIP, 4 Britain, Brexit party, some Labour, Liberals, Greenies and many neutral voters voting for Brexit when they vote for Boris. If Boris gets a landslide victory, or a big majority, then Corbyn may well be forced to stand down, Corbyn himself won't want that, but Labour MP's will.
What also has to be took into consideration is all those who didn't vote in the original referendum.
They've stood by and watched all the scaremongering by the remainers, they've seen their own constituant MP's lie and stab them in back. They've seen how the EU have acted toward the UK and Brexit, they've seen the lies, deceit and evil from the EU corrupt, remoaner MP's and the remoaner mob......................These people will be the silent majority that swings the GE for Boris, or are brainwashed by the remoaners evil doings...........My money's on the former.
