President Sarkozy denies claims that his presidential campaign was funded illegally by France's richest woman, but the affair has brought his popularity to an all-time low. 87-year-old Bettencourt reportedly has a net worth of €17 billion, largely in holdings of stock in cosmetics giant L’Oréal. The scandal was first brought to light by her daughter, Francoise Bettencourt-Meyers. It started out as a legal dispute over the family fortune between the two, but when prosecutors opened a separate investigation into Liliane Bettencourt's tax affairs, her political connections came under the spotlight - including her donations to Sarkozy's conservative party, the UMP. Even her butler and her accountant have given their version of events.
