The Benn Bill keeps No Deal at bay for 3 months. And even Johnson must realise that defying the Commons and refusing to extend at the European Council is a bad look.
They’d have to go into an election having broken the leave-by-31-Oct pledge.
Plus Johnson is even more of a hate figure than May was on the Labour benches.
There aren’t enough MPs who’d back a Deal.
So he would face a General Election shortly after a Deal had been approved.
Keep this in mind as talk of a Deal increases.
If, when the Commons returns mid October, Corbyn were to say ok, No Deal is off the table until January, so Johnson you can have your General Election now, can Johnson actually refuse?
Having pushed so hard for a GE so recently I doubt it.
But look at the bigger picture and it’s still a very long shot and has dangers for Johnson.
