Education Secretary Michael Gove is to become the new chief whip in the most wide-ranging cabinet reshuffle of David Cameron's premiership.
He has been replaced by Treasury minister Nicky Morgan, as Mr Cameron promotes more women into top jobs.
Ken Clarke is among the old guard to have stood down and Foreign Secretary William Hague has moved to a lower profile role as Commons leader.
