She's entirely wrong and lying, he literally and demonstrably campaigned for remain.
He CAMPAIGNED for Remain, at about a 7/10 level, and when he wasn't taking holidays. But he didn't FIGHT for Remain. We all know what Corbyn fighting looks like. That Corbyn was conspicuously absent during the Referendum.
He campaigned for something he isn't fully behind but knew to be the better option, than brexit as termed then, let alone the no deal now. I don't really see that as a bad thing, but also, he's certainly not a Brexiteer as her obviously false and pointless tweet states.
