Sir Richard Leavis

Richard Leavis is the Prime Minister's Principal Private Secretary. An unelected civil servant, he has more experience of the nuts and bolts of government than almost anyone else on Ros' team. Discreet, loyal and professional, he does whatever he can to smooth Ros' way through the mind-boggling tangle of government.
