An Oxford University professor and government adviser on tackling extremism is facing new allegations including sexual misconduct with minors.
Prof Tariq Ramadan was accused of rape last month by a French feminist author. He has denied the allegation and said he will sue for libel.
He is now facing new accusations from four Swiss women who say he made sexual advances to them when they were studying under him as teenagers in Geneva.
One of the women told Tribune de Geneve newspaper Prof Ramadan made unsuccessful sexual advances to her when she was 14 years old.
Another alleged he had sexual relations with her in the back of his car when she was 15 years old.
