Radha Bhatt has demanded in a legal letter that Universities UK (UUK), which represents all vice-chancellors in the UK, admit that a guidance on segregation it published last November was "unlawful".

UUK's guidance had cited a case study to justify its policy of allowing the "voluntary" separation of men and women for religious purposes.

It was forced to withdraw the case study last month and to review its guidance after Prime Minister David Cameron said he wanted to ban segregation at universities.

Bhatt, a 19-year-old first-year history student, believes that the UUK guidance is a threat to women of all backgrounds.
