Michael Gove's adviser attended a meeting in 2010 where concerns about an alleged plot by Muslim hardliners to takeover some Birmingham schools were raised, the Independent says. Mr Gove said he was unaware of his department's Trojan Horse warnings.
Sir Michael Wilshaw has issued a statement clarifying that it was he, not Michael Gove, who took the decision not to introduce no-notice Ofsted inspections in schools.
The head of the schools watchdog said: "When I first became chief inspector in early 2012, I set out plans to introduce no-notice inspections for all schools as part of a wider package of reforms to improve the inspection system.
"As a result of representations I received from headteachers and others during the consultation, I decided to move instead from two days' notice to much shorter half-day notice inspections from September 2012."
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.
