Allegations of widespread misspending by the UN High Commissioner for Refugees could make it harder for the body to raise money for its work from donor governments. Costs were said to include US$50,000 (HK$387,000) on chartering a private jet by a senior official who was formally responsible for resolving Hong Kong's boat people problem. UN Secretary-General Kofi Annan has said he will look into the allegations of dubious accounting amid concerns donor governments might withhold funding. The allegations came to light after parts of the body's internal audit were leaked before the post of commissioner, now held by Sadako Ogato, comes up for review at the end of this year. The audit report says the UN body spends up to 30 per cent of its budget on administration and staffing. But its mandate demands that at least 80 per cent of its budget be spent directly on the welfare of an estimated 22 million refugees and displaced people worldwide. None of the allegations covers the funding for the body's work in caring for the Vietnamese boat people in Hong Kong or elsewhere in Asia. Questions have been raised about the spending by assistant commissioner Sergio Vieira de Mello in chartering a private jet for himself and another official during emergency work dealing with Rwandan refugees in 1996. Mr Vieira de Mello was in charge of negotiating a solution to Hong Kong's boat people problem. A spokesman at the refugee body's headquarters in Geneva insisted the information leaked to the press did not reflect the full state of the finances. 'These allegations are based on an external audit for 1997 which has been leaked to the press in bits and pieces. In fact the final report gives us a clean bill of health,' the spokesman said. But he admitted that, working in 114 countries in conditions which were often difficult, the agency did sometimes encounter problems auditing funds. 'From time to time, we have problems here and there but there has been no crookedness,' he said. Mr Vieira de Mello's decision to charter a jet had been taken in extreme conditions and he had since fully justified the expenditure. A spokesman for the British Government, one of the biggest donors, said officials were discussing spending with the refugee body. 'There are some areas in which we think the body has to tighten up spending and we are looking at ways in which they can improve,' a spokesman at the British Department of International Development said. The SAR Government is still owed HK$1.2 billion to cover the costs of caring for Vietnamese boat people.
