Jo Johnson: PM's ex-aide 'so wrong' about Justine Greening
Theresa May's former adviser has sparked criticism for a newspaper article attacking ex-education secretary Justine Greening.
Nick Timothy said Ms Greening - who quit in the reshuffle after the PM tried to move her to another department - had resisted attempts to reform school and tuition fees policy.
This claim was branded "so wrong" by ex-universities minister Jo Johnson.
Mr Johnson said Ms Greening had been "faultlessly loyal".
Mr Timothy, who quit Downing Street after playing a key role in the Conservatives' unsuccessful general election campaign, has since become a newspaper columnist.

"Charged with making Britain 'the world's great meritocracy', she put the brakes on policies that work, like free schools, and devised bureaucratic initiatives of little value," he wrote.
He denied allegations that he had "orchestrated" Ms Greening's departure from her post, but backed the decision to replace her with Damian Hinds. He also accused her of blocking proposals to cut university tuition fees.
