Education Secretary Michael Gove has insisted that the government is "perfectly happy to appoint people whatever their political background to important jobs".
Speaking of the outgoing chair of Ofsted Baroness Morgan, who has accused No 10 of trying to fill public bodies with Tory supporters, Mr Gove said "she's done a really good job".
But he told BBC 1's Andrew Marr Show that he felt it was necessary to replace her "in order to bring new eyes to bear".
