Leading universities have been named by David Cameron for giving a platform to extremists as a new legal duty on institutions to "protect impressionable young minds" was announced.
The following universities were identified as holding the most events, according to Downing Street.
The University of London's Queen Mary
School of Oriental and African Studies (Soas)
Among the speakers were Haitham Al-Haddad, Dr Uthman Lateef, Alomgir Ali, Imran Ibn Mansur, also known as Dawah Man, Hamza Tzortis and Dr Salman Butt, who have all publicly denounced British values.
Whitehall's Extremism Analysis Unit claimed at least 70 events featuring hate speakers were held on campuses last year.
Security officials also have concerns about the number of young people being radicalised and travelling to join Islamic State jihadists.
Under plans announced by the Prime Minister, who is chairing a meeting of the extremism task force, universities will be forced to combat extremism on campus.
The updated Prevent duty guidance will come into force at higher education institutions on September 21.
It will require universities to put in place policies to stop extremists radicalising students and tackle gender segregation at events
Universities will have to have proper assessment processes for invited speakers and ensure those with extremist views do not go unchallenged.
It follows the imposition of similar duties on public bodies including councils, prisons, NHS trusts and schools in July.
