Serco and G4S chief executives stand down
The chief executive of services provider Serco and the UK chief executive for security firm G4S have both resigned from their respective roles.

The chief executive of services provider Serco and the UK chief executive for security firm G4S have both resigned from their respective roles.
Christopher Hyman, who had been in his role since 2002, has left Serco with immediate effect.
He has been temporarily replaced by the head of the companys Americas division Ed Casey while a permanent chief executive is sought. Serco confirmed it is looking outside the company for its next chief executive.
The resignation coincides with a reorganisation of the company, including splitting its government work into separate businesses to allow for close monitoring.
Richard Morris, the UK chief executive of G4S, also resigned, with chief operating officer Eddie Ashton taking over.
Mr Morris took up the role in September 2012 and had been with the company for ten years.
Both companies have faced criticism after allegations emerged that they had charged the Government for tagging criminals who were dead, in prison or who had not been tagged in the first place.
The scandal has prompted a Government review of the contracts held by Serco and G4S. The Serious Fraud Office is investigating both firms over the claims.
