Britain's Home Secretary has accused universities of complacency in tackling Islamic extremism and radicalization on campus.

Theresa May says universities have not been taking the issue of radicalization seriously, unwilling to recognize that extremists can form groups on campus "without anyone knowing."

She told Britain's Daily Telegraph newspaper on Monday that universities can do more to combat extremism and need to be prepared to "send very clear messages" and "ask themselves some questions about what happens on their campuses."

Britain has spent about 80 million pounds ($140 million) on a project aimed at preventing young people from embracing violent extremism.

A review of the project is to be published this week amid concerns it is not working.
