PARIS, Oct 4 (Reuters) - Societe Generale, France's third-biggest bank, named Marie-Christine Ducholet as the head of its new French retail banking unit - an area targeted as a high priority for the bank and its new group chief executive.

The appointment of Ducholet, who joined SocGen in 1985, comes just a few days after SocGen appointed internal investment banking boss Slawomir Krupa as its new group chief executive. (Reporting by Sudip Kar-Gupta, Editing by Louise Heavens)
