Former chief secretary Anson Chan Fang On-sang and Civic Party lawmaker Alan Leong Kah-kit have dropped out of a list of top 10 most visible political figures, according to a University of Hong Kong poll. Unionist legislator Lee Cheuk-yan and Legco president Tsang Yok-sing move onto the list. Chief Executive Donald Tsang Yam-kuen retains his top spot, in a survey of 1,003 respondents earlier this month.
