In a statement on behalf of the university in Preston, Lancashire, the spokesperson said: “The UK government has formally adopted the International Holocaust Remembrance Alliance’s new definition of what constitutes antisemitism.
“We believe the proposed talk contravenes the new definition and furthermore breaches university protocols for such events, where we require assurances of a balanced view or a panel of speakers representing all interests.”
He added: “In this instance our procedures determined that the proposed event would not be lawful and therefore it will not proceed as planned.”
The talk was scheduled to take place as part of a week of anti-Israel events expected to be held at universities nationwide.
The North West Friends of Israel group welcomed the move. Co-chair Raphi Bloom said NWFoI had led a campaign to ban the event.
"Universities across the UK have signed up to the government's definition of antisemitism and have a duty of care to their Jewish students - and staff - to ensure that they do not feel intimidated or abused on campus," he said.
