Anson Chan
DAB chairman Ma Lik's death in 2007 triggered the 2007 Hong Kong Island by-election, where the pro-democracy and pro-Beijing camps each fielded former senior government officials against each other. Former Chief Secretary for Administration Anson Chan won the crowded-fielded pro-democracy primary, while former Secretary for Security Regina Ip who was the face of the 2003 Basic Law Article 23 legislation was supported by the pro-Beijing parties. Receiving wide attention, Anson Chan eventually beat Regina Ip with 55–43 vote share.
