The chief inspector of schools has said he is "spitting blood" over right-wing attacks on Ofsted.
Sir Michael Wilshaw told The Sunday Times that education secretary Michael Gove risked damaging school standards by undermining his authority and attacking Ofsted's ideology.
It comes after reports that right-wing think tank Civitas has urged the Government to create a new body to inspect free schools and academies.
While the Policy Exchange think tank, which Mr Gove set up in 2002, is calling for evidence from schools about whether the school inspection body is "fit for purpose".
