May made Damian Green, former work and pensions secretary, her deputy by naming him first secretary of state.
Treasury chief secretary David Gauke moves in to take Green’s place, while the leader of the House of Commons, David Lidington, becomes justice secretary.
Lidington’s move sees him replace Liz Truss, who has faced criticism in the justice role and has been moved by May to Gauke’s former post as treasury chief secretary.
