REUTERS/Carlos JassoMEXICO CITY/WASHINGTON, Sept 20 (Reuters) - An independent investigation found evidence that the Inter-American Development Bank's (IDB) chief, Mauricio Claver-Carone, engaged in an intimate relationship with a staffer, in a review by an outside firm prompted by whistleblower allegations, two sources briefed on the probe told Reuters. The findings of the months-long investigation were presented by legal firm Davis Polk to the bank's directors on Monday. It was solicited by the IDB to investigate allegations leveled against Claver-Carone in a whistleblower email at the end of March. A relationship between Claver-Carone and someone he directly managed at the bank would appear to violate the IDB's ethics code. The staffer, in written testimony submitted to investigators, denied "all allegations that suggest any violation of the staff code" and said she had not received any written notification of any allegations.
