People's confidence in Chief Executive Donald Tsang Yam-kuen has fallen, and dissatisfaction with his government's performance on everything except its maintenance of economic prosperity has risen to a five-year high, according to a survey conducted by the University of Hong Kong. The survey of 1,012 respondents carried out late last month found confidence in Tsang had dropped by 4 percentage points to 38 per cent since a similar poll in early March. The proportion voicing no confidence in the chief executive rose by 4 percentage points to 46 per cent. Satisfaction with the Tsang administration's handling of relations with the central government was down 10 percentage points, to 50 per cent, compared with a survey conducted in December. Dissatisfaction with the government's efforts in protecting human rights and freedom rose by 6 percentage points to 34 per cent, and 43 per cent of respondents said they were dissatisfied with the pace of democratic development. The findings have a margin of error of plus or minus 3 percentage points.
