The popularity rating of Donald Tsang Yam-kuen has soared to a four-year high in the days since he became acting chief executive. Mr Tsang's rating climbed to 70.4 marks out of 100, far outstripping Tung Chee-hwa's by 22.5. Mr Tsang's 'honeymoon period' has also spilled over to the entire government, with the public satisfaction rate with the administration rising by 11 percentage points to 31 per cent. The University of Hong Kong poll found that Mr Tsang's popularity rose from 63.7 in the previous poll, carried out from March 1 to 3. Mr Tung's approval stood at 47.9 when he resigned last week. The latest poll, carried out on Wednesday, showed that 68 per cent of the 1,041 respondents supported Mr Tsang to be chief executive. Mr Tsang had consistently topped the popularity polls during the Tung administration. Robert Chung Ting-yiu, director of the university's Public Opinion Programme, attributed the soaring marks to the 'advantage of changing the chief executive', but said maintaining the advantage depended on Mr Tsang's performance in the coming months.
