The organisation which represents Muslim students has held its first conference on campus extremism.
The Federation of Student Islamic Societies' Radical Thinking event took place at UCL last Friday.
It heard from speakers including David Knowles, a police liaison officier with the government's Prevent anti-terror strategy, and Mehri Niknam of the Joseph Interfaith Foundation.
Fosis, which represents more than 90,000 Muslim students in Britain, has previously been criticised for its reluctance to criticise, or end, invitations to hate speakers.
The Union of Jewish Students said the conference had not done enough to tackle the issue.
Carly McKenzie, UJS campaigns director, said: "It's worrying the lengths that Fosis will go to defend the speakers that they have invited onto campus. There is a distinct level of hypocrisy that Fosis is promoting freedom of speech on campus while they actively support the banning of the BNP."
Ahead of the conference, Fosis president Nabil Ahmed had said: "It's time to talk, seriously and openly."
