Two people were asked to leave an anti-Israel event at Sussex University last Thursday.
The event, which was held to coincide with Israel Apartheid Week, was organised by students from the university's Friends of Palestine group at a campus lecture theatre.
Members of the Boycott, Divestment and Sanctions group, including anti-Israel activist Therezia Cooper, were invited to speak at the event , which was attended by around 80 people.
A Sussex University spokesperson confirmed that there was “extra security to ensure the event could take place safely and peacefully” after members of Sussex Friends of Israel said they would picket the event if they were not granted admission.
