A former schools governor in Birmingham has told ITV News he raised concerns over the threat of Islamist extremists on schools back in 2008.
Ofsted is expected to strip a schools across Buckingham of their current status, over concerns they are not doing enough to protect children from extremism.
Currently more than 20 schools across the city are reported to be implicated in some of the allegations. Former schools governor Keith Townsend said:
"The conspiracy seemed to be, either to turn the school into an entirely Muslim faith school, or to give Muslim children some form of ascendancy over those from other faiths."
ITV News Correspondent Rupert Evelyn reports.
The leaking, from her department, of a letter to Michael Gove, raises serious questions for the Home Secretary to answer.
One school was praised by Ofsted for using money from the pupil premium to pay for a number of cultural trips to Saudi Arabia.
Six Birmingham schools will be rated 'inadequate' and several more downgraded. Council officials have been criticised for failing to act.
