Chief Secretary Rafael Hui Si-yan is the third-most popular government minister, despite suggestions that his closeness to property developers would affect his handling of the West Kowloon cultural hub project. In the latest monthly popularity rankings by the University of Hong Kong's public opinion programme, Mr Hui scored 60.5 points on a scale of 100. This sandwiched him between Secretary for Security Ambrose Lee Siu-kwong with 61 points, and Secretary for Economic Development and Labour Stephen Ip Shu-kwan with 59.8. Financial Secretary Henry Tang Ying-yen, who saw a slight improvement of 0.7 over his score of 63.7 a month ago, was the only other minister to enjoy higher marks than Mr Hui. Chief Executive Donald Tsang Yam-kuen's score has remained above 70 since a survey in May, when he announced his bid for top post. His latest rating slipped almost one point to 71.4, but 77 per cent of the 631 respondents supported him as chief executive. Programme director Robert Chung Ting-yiu said Mr Tsang's high popularity may have helped Mr Hui to attain a high rating in the short time since he took office.
