On 28 June 1991, he became head of the Committee for External Relations of the Mayor's Office, with responsibility for promoting international relations and foreign investments and registering business ventures. Within a year, Putin was investigated by the city legislative council led by Marina Salye. It was concluded that he had understated prices and permitted the export of metals valued at $93 million in exchange for foreign food aid that never arrived. Despite the investigators' recommendation that Putin be fired, Putin remained head of the Committee for External Relations until 1996. From 1994 to 1996, he held several other political and governmental positions in Saint Petersburg.
