According to the Sunday Times, there has been anger in Muslim areas of Bradford, Luton and the Tower Hamlets borough in east London where a further five schools are being investigated.

Michael Wilshaw, chief inspector of Ofsted, had found in his report that "a culture of fear and intimidation has taken grip" at some Birmingham schools.
