I’m old enough to remember when robust debate was part and parcel of university life, then we would all go off to the student union.
Neither students nor staff should face abuse or aggression for engaging in debate, or listening to ideas with which others disagree.
Due to escalating disruptive protests, I have decided to cancel the remainder of these lectures. This is deeply lamentable, but the disruption has undermined the academic nature of this series. Students shouldn't face bullying or harassment when attending academic events.
