Not exactly shocking news.

Via Telegraph:

More than 100 independent faith schools may be radicalising students, the Department of Education has warned in a secret memo which admits that officials are struggling to tackle extremism in state and private schools.

Michael Gove, the education secretary, was one of the key voices calling for a ban on support for non-violent extremism when it published its Prevent strategy to fight radicalisation last year.

But behind closed doors there are concerns about 118 “socially conservative” independent faith schools – the vast majority of them Muslim – where pupils may be encouraged to cut themselves off from mainstream society.

Ministers have been told they do not have “detailed information” about the religious orientation of the groups and movements behind all independent faith schools.
