The International Monetary Fund is investigating allegations that its chief, Dominique Strauss-Kahn, had an improper relationship with a female employee.
IMF lawyers have opened an independent probe into the charges, first reported Saturday by The Wall Street Journal.
The probe will look into whether Strauss-Khan abused his power as IMF managing director by showing favoritism to Piroska Nagy - an IMF official who has since left the fund.
Strauss-Kahn is a former French finance minister. He denies ever abusing his position at the fund, and says he is cooperating with investigators.
A report on the case is expected by the end of the month.
Last year, Paul Wolfowitz resigned from his position as World Bank president after authorities found he had arranged a promotion and generous pay package for his bank employee girlfriend.
Some information for this report was provided by AFP, AP and Reuters.
