Secretary-General Kofi Annan expects to be exonerated by the investigation into the UN oil-for-food programme in Iraq, but his son's situation may be 'very different' and must be judged on its own, the UN leader's chief of staff said. Former US Federal Reserve chairman Paul Volcker is scheduled to issue a report on Tuesday on his investigation into the activities of the secretary-general and his son Kojo, who worked in Africa for a Swiss company that was awarded an oil-for-food contract. The Financial Times and the Italian business newspaper Il Sole 24 reported yesterday that Kojo Annan received at least US$300,000 from the company, Cotecna Insection, almost double the amount previously disclosed. The two papers, which conducted a joint investigation, also reported that the secretary-general met top executives from Cotecna twice before the oil-for-food contract was awarded in December 1998 and once afterwards. Mark Malloch Brown, the secretary-general's chief of staff, confirmed three meetings, and said they had been 'fully disclosed' to the Volcker committee. None of the meetings 'had anything to do with Cotecna's bid', he said. 'The secretary-general believes that it [the Volcker report] will clearly vindicate him, in that it will describe these meetings in great detail and no doubt, in his mind, confirm the fact that they were innocent encounters,' Mr Malloch Brown said. 'The secretary-general has consistently maintained that he himself is not guilty of any wrongdoing and that he believes the undertakings that his son has given him - that Kojo's work for Cotecna had nothing to do with the contract,' he said. So far, Mr Malloch Brown stressed, there have been no findings on Kojo Annan. 'If some of what we see in The Financial Times is confirmed, that's going to create a very different situation but for Kojo, not for the secretary-general,' Mr Malloch Brown said. Kojo Annan's actions 'will have to be judged on their own rights as to whether they were appropriate or not', he said. Mr Volcker will also address whether Kojo Annan's actions 'are in any way linked to the secretary-general', he said. 'We stand by it - that we believe on Tuesday that the secretary-general will be exonerated of any wrongdoing, but like you, we have to wait for the report,' Mr Malloch Brown said. A spokesman for Cotecna said the company has been co-operating fully in assisting the Volcker inquiry 'to clarify any and all outstanding questions concerning payment to Kojo Annan'. Robert Massey, Cotecna's chief executive, met Mr Volcker and his investigators in New York on Monday to discuss the discrepancies in the reported payments to Kojo Annan and the company's ongoing audit to determine the correct amount, the spokesman said. The spokesman said the three contacts between Cotecna executives and the secretary-general were reported to Mr Volcker and other bodies investigating the US$63 billion UN humanitarian programme in Iraq. Kojo Annan worked for Cotecna in West Africa from 1995 to December 1997 and then as a consultant until the end of 1998.
