Education Secretary Michael Gove has said in a statement that anyone working for him that attempts to undermine the position of the chief inspector of schools, Sir Michael Wilshaw, would be instantly dismissed.
His comments come as Sir Wilshaw said in a newspaper interview that he is "spitting blood" over attacks on Ofsted by two right-wing think tanks.
Sir Michael Wilshaw is a superb professional and an outstanding chief inspector. He is making the changes Ofsted needs to help raise standards further.
No-one working for me has had anything to do with any campaign against him or briefing against him. No one working for me has sought to undermine his position. Anyone who did would be instantly dismissed.
