yet that is very nearly what transpired.
But it didn't. The possibility of no deal was used to bring the EU back to the negotiating table. And guess what, it worked. Despite saying that they would not renegotiate, they did, and Boris got his deal. Parliament then, for party-political reasons, refused to support it. The LibDems out of principle, and fair play to them, but the Corbynites refused just because they wanted to obstruct the government and make it look bad. Instead they just made themselves look bad. Now they've got an election, and the lowest approval ratings in decades for an opposition leader. We shall what those millions want in a little over 3 weeks.
