Societe Generale has called in US giant Skadden Arps Slate Meagher & Flom to battle a class action law suit brought by shareholders following recent heavy losses sustained by the French lender.

The class action has been filed against SocGen, France’s second-largest bank, by a shareholder in the US as a result of losses sustained following its exposure to sub-prime loans and alleged fraudulent dealing by employee Jerome Kerviel.
