Claims of a deteriorating bureaucracy have seen Hong Kong lose top spot to Singapore in an annual efficiency survey of executives. The Political and Economic Risk Consultancy says an exodus of civil servants has 'stretched the supply of experienced manpower'. 'Viewed optimistically, the grade is still very favourable, indicating that the local civil service is sticking to its high standards despite the heavy workload,' it says. The study warns that in the few areas where the public have direct dealings with government officials, bottlenecks have developed. Hong Kong was still ahead of Britain, the US and Australia. At the bottom of the 15-strong list were Indonesia, South Korea and Vietnam. China ranked 11th.
