LogicaCMG on Tuesday said it had picked Andy Green, a director of BT Group, as its new chief executive. He will fill the gap left when Martin Read resigned after the IT services group issued a profit warning in May related to problems in its UK business.

The board has seen some turmoil since Mr Read announced his departure, with a new chairman, David Tyler, selected to replace Cor Stutterheim. In July Didier Herrmann, head of the group’s French, German and Swiss business was “asked to step down” and replaced by Patrick Guimbal.
