PSA said Beatrice Foucher, currently deputy DS chief executive and an ex-Renault manager, would succeed Yves Bonnefont as DS CEO.

The company said in a statement that Vincent Cobee, currently deputy Citroen CEO and a former Nissan and Mitsubishi executive, would replace Linda Jackson as Citroen CEO.

PSA, which is in the midst of a merger with Italy's Fiat Chrysler, said Bonnefont would lead a study on potential costs savings within the group.
