|Shadow education secretary - David Willetts
Nick-named "two brains", Mr Willetts has played a core role in shaping previous Tory manifestos.
In past shadow cabinets he has served as policy coordinator, shadow work and pensions secretary and most recently as shadow trade and industry secretary.
He is seen as a moderniser, but backed David Davis in the leadership race.
Mr Willetts became an MP in 1992 and was promoted by John Major to be Paymaster General. But he resigned after falling foul of the Commons standards and privileges committee.
