CHANCELLOR George Osborne confirmed yesterday that Education Secretary Michael Gove and Home Secretary Theresa May are under investigation for their public infighting over Islamic extremism in schools.

Mr Osborne said that Prime Minister David Cameron had asked Cabinet Secretary Sir Jeremy Heywood to subject the pair to scrutiny.

The dispute spilled into the public domain with the publication of a letter in which Ms May questioned the Department for Education’s response to allegations that extremists had attempted to infiltrate schools in Birmingham.
