Almost 80 per cent of respondents to a Hong Kong opinion poll demanded an independent committee be set up to investigate the Sars outbreak. The telephone survey of 1,238 people carried out by the Democratic Party last week also found that more than half believed the legislature should head the investigation to pinpoint any flaws in the health system that allowed the virus to spread. About 79.6 per cent of the poll's respondents said an independent investigation committee should be formed. Last week, Chief Executive Tung Chee-hwa said the Secretary for Health, Welfare and Food, Yeoh Eng-kiong, would set up a review committee to examine the outbreak. About 52 per cent of respondents said Dr Yeoh should not head the committee, favouring the Legislative Council instead. Democrat chairman Yeung Sum, who wants a Legco select committee should be set up, said the Breakfast Group of non-affiliated legislators would support him.
