Ex-French president Nicolas Sarkozy was placed under formal investigation on Thursday for “abuse of weakness” in a 2007 party funding case involving elderly L’Oreal heiress Liliane Bettencourt, the public prosecutor said.
The risk for Sarkozy, unseated May last year but considered a potential conservative candidate in the 2017 presidential race, is that he may end up plagued by suspicion for months or years, even if his lawyer says there is no case against him.
Under French law, a formal investigation is the final step before a suspect is accused of a crime. Sarkozy, who only this month hinted he could make a political comeback, repeatedly has denied taking campaign funds from Bettencourt.

The 90-year-old Bettencourt is France’s richest woman. Sarkozy, who lost last year’s election to Socialist Francois Hollande, faced members of her staff at the hearing earlier on Thursday.
