The head of Theresa May's new anti-extremism commission - set up after the Manchester Arena attack - is facing calls to quit from Muslim groups.
Sara Khan, who has campaigned for women's rights in Muslim communities, has been given the task of rooting out extremism in the UK.
She has promised "zero tolerance to those who promote hate".
But her support for the Home Office's Prevent strategy has led to claims she is too close to the government.
Downing Street has insisted Ms Khan is "expertly qualified" for the new role - but a number of Muslim organisations are understood to be calling for her to be sacked and saying they will not work with her.
