Some of the hardline members even refuse to speak to female Muslim members of staff at the University of Westminster, the independent panel said. But university officials underplayed this "sometimes hostile or intimidatory" behaviour towards women "for fear of appearing Islamophobic", they added. The report was commissioned earlier this year after fears about extremism on its campuses.

In February the notorious killer known as Jihadi John was unmasked as former student Mohammed Emwazi, 27. He studied Information Systems at the university between 2006 and 2009 but there is no evidence to suggest he was radicalised there. After he was identified the university's suspended any Students' Union event deemed "sensitive". Among the events was an address by controversial preacher Sheikh Haitham al-Haddad, who has reportedly referred to homosexuality as a "criminal act". In 2013, Haddad gave a speech at the university and talked of a future in which Islam was "one of the superpowers of the world". He added: "Everyone will enjoy the benefits of Islam."

The panel also revealed the society did not appear to hold democratic elections and was instead run by a "self-perpetuating in-group". Members of this in-group acted as "apostles of a self-contained faith" and were concerned with "matters of religious orthodoxy and perceived heresy”, they added. Their report was made public just over a week ago but Express.co.uk revealed some of its most damning findings in June.

Fiyaz Mughal, one of the panel's four members, described the society as a "breeding ground for very ultra-conservative views". He told the Guardian it was a mistake to let the "far too divisive" al-Haddad speak, but said staff were doing their best to balance the needs of a diverse student body. The Islamic Society and Students' Union did not comment on the findings. Geoff Petts, the university's vice-chancellor, said Westminster had tightened rules on external speakers.
