Christine Lagarde, the head of the International Monetary Fund, has been placed under formal investigation in France for her alleged involvement in a long-running fraud case.
Under French law, a formal investigation means prosecutors believe they have serious evidence implicating a suspect in a crime. It does not necessarily lead to charges or a trial.
The case stems from 2008 when Lagarde was finance minister under former French President Nicolas Sarkozy.
Prosecutors believe that Lagarde was negligent in dealing with a case in which a supporter of Sarkozy — Bernard Tapie — was awarded a settlement worth $285 million euros plus interest.
Tapie had sued the French state in 1993 after selling a stake in Adidas to Credit Lyonnais, which was owned by the government. Tapie claimed Credit Lyonnais defrauded him when it resold the stake at a far higher price. The bank has denied wrongdoing.
Lagarde has not been accused of profiting personally from the Tapie case. The issue is whether she gave Tapie preferential treatment, by actions such as overruling other officials and referring the case to arbitration.
Lagarde said she would appeal the decision to be placed under formal investigation, saying the move was “without merit.”
The IMF said Wednesday that Lagarde will continue in her role at the organization but had no further comment.
