Gillian Keegan’s special adviser will return to a civil service role as senior schools policy adviser at the Department for Education.
Rory Gribbell will be filling the role left vacant by David Thomas, who is now running a fledging maths charity.
Gribbell has held his current role since September. He was recruited to advise then secretary of state Kit Malthouse, who lasted just over a month before being replaced by Keegan.
A Teach First alumnus, Gribbell previously led on education policy in Dominic Cumming’s Number 10 policy unit.
