Well the one and only reason that the Tory referendum, then Article 50, were ratified is that the steamroller was already in full flow and that any party which voted against either would have been toast. We call it realpolitik. I state this to explain it, not excuse it, which I definitely don't. And please give over about politicians' "promises." Anyone using that to cast the Tories as the noble beasts in all this are exhibiting the very epitome of disingenuousness. To the point of dishonesty, actually.
