In an extract from the letter Theresa May wrote to Michael Gove raising questions about his department's treatment of Islamic extremism in schools, she asks directly "why did nobody act?"
How did it come to pass, for example, that one of the governors at Park View was the chairman of the education committee of the Muslim Council of Britain?
Is it true that Birmingham City Council was warned about these allegations in 2008?
Is it true that the Department for Education was warned in 2010? If so, why did nobody act?
I am aware that several investigations are still ongoing and those investigations are yet to conclude.
But it is clear to me that we will need to take clear action to improve the quality of staffing and governance if we are to prevent extremism in schools.
