This coming year, I'm planning to teaching this piece by Catriona McKinnon on Holocaust denial. So, I've been paying some attention to recent debates over freedom of speech.
Bridget Phillipson has announced that the Labour government will be pausing implementation of the previous government's Higher Education (Freedom of Speech) Act 2023, partly because (she suggests) it might protect Holocaust denial. An official statement can be found here.
This move has been welcomed by students or, at least, the NUS. (Presumably student opinion isn't unanimous.)
