Who is to blame in schools extremism row?

The Education Secretary, Michael Gove, has ordered an inquiry into the role of Ofsted and whether his department ignored warnings about religious extremism in schools.

The move came after the regulator said "a culture of fear and intimidation" had emerged in some Birmingham schools caught up in the "Trojan Horse" claims.

Meanwhile Home Secretary Theresa May has told MPs she did not authorise the leak of her letter to Mr Gove about the row.
