Former Miss Hong Kong finalist Erica Yuen Mi-ming was elected chairwoman of radical pan-democratic group People Power last night. Yuen, 32, an executive committee and founding member of the group, was elected to the position in a unanimous vote by all 15 members. Dentist Dr Yim Tat-ming, also on the committee, was elected vice-chairman of the group - a newly created role. Lawmaker Raymond Chan Chi-chuen and committee member Thomas Yan Sun-kong retained their positions as the other two vice-chairmen. Yuen said: "I'm glad to be elected. I hope that I will be able to lead People Power well." The election was triggered by the resignation of Christopher Lau Gar-hung as chairman. He announced his departure last month, four weeks after the shock resignation of the group's lawmaker founder Raymond Wong Yuk-man, who had reportedly expressed discontent to Lau over the group's stance on universal suffrage in the 2017 chief executive poll. Yuen was one of the five finalists in the 2005 Miss Hong Kong pageant, in which she won the Tourism Ambassador title. She went on to work for TVB as an actor and presenter until an acrimonious dispute over her contract renewal in 2007, after which she left the station. Last year, she announced she would run for the Legislative Council as a People Power candidate for the New Territories East constituency with Raymond Chan, but only Chan won a seat. Yuen said last night that the group faced a challenging time, but it was a time of opportunity. She aimed to galvanise more support for the group, particularly through social media. It does not yet take members. Asked if she was tough enough to front the radical political grouping, Yuen said: "I've always been aggressive. I dared to take on TVB. I dared to take on the Democratic Party for betraying democracy when it negotiated with Beijing on political reform. I'm not a moderate." Former chairman Lau, who will remain on the executive committee, was quick to endorse Yuen as the new chairwoman. "She is familiar to a lot of people. We believe she can bring the group's ideals to a broad range of people. It will help fuel the promotion of democracy," he said.
