Schools at the centre of the 'Trojan Horse' allegations used inspections notice "to evade proper scrutiny", Education Secretary Michael Gove said.
We have to ensure children are safe in our schools. Evidence uncovered in Birmingham clearly indicates that schools have used the notice they have been given of inspections to evade proper scrutiny.
Sir Michael Wilshaw will now examine the practicalities of moving to a position where all schools know they may face an unannounced inspection.
Our children need to be protected in schools, kept safe from the dangers of extremism and guaranteed a broad and balanced curriculum.
This change will help provide parents with the reassurance they need.
Michael Gove's assertion that new rules could force schools to actively promote "British values" has sent the Twittersphere into a frenzy.
Five schools investigated in the wake of "Trojan Horse" claims will be put in special measures, while a sixth with remain under sanctions.
