Labour has called on the Home Secretary Theresa May to explain the part she played in a row with the Education Secretary Michael Gove, over how to deal with extremism in schools.
Mr Gove has publicly apologised to David Cameron, and to a senior civil servant whom he had criticised.
Speaking on the Andrew Marr Show, Ms Cooper said: "I think Theresa May needs to come out publicly and answer what she did to publish this letter."
