'Trojan horse': Ofsted chief Wilshaw on 'culture of fear'
Ofsted has put three schools in special measures following reports into the alleged "Trojan Horse" plot.
The watchdog was called in after allegations of a hardline Muslim takeover of schools in Birmingham and has now inspected 21 schools.
One trust has denounced Ofsted's decision, saying the body had come to its schools "looking for extremism".
However, Ofsted chief Sir Michael Wilshaw described some of the findings as "deeply worrying and in some ways quite shocking".
"In the most serious cases a culture of fear and intimidation has taken grip since the schools were last inspected", he added.
