The Conservatives have been accused of making a "determined effort" to put Tory supporters in charge of public bodies.
The claim has been made by the Labour peer Baroness Morgan, after she was told she would not be re-appointed as head of the schools inspectorate, Ofsted.
A Downing Street source has called her claim "baseless".
