The District Council Elections in 2007 saw the great bounce back of the DAB by winning 115 seats, more than a quarter of the seats in the district level, far ahead of other political parties. Gregory So resigned as the vice-chairman and was succeeded by Ann Chiang when he was appointed as the Under Secretary for Commerce and Economic Development by Chief Executive Donald Tsang in May 2008, among other DAB members appointed to the government. Gregory So was later revealed by the media as having Canadian citizenship, which he had to renounce as a result. The scandal became an electoral issue in the following 2008 LegCo Election that the pan-democracy camp used to attack the DAB candidates. Nevertheless, the DAB remained as the largest party in the Legislative Council in the election, winning 13 seats in total (if including the FTU candidates who had DAB membership). Chan Yuen-han and Wong Kwok-hing were founding members of the DAB and used to run for the DAB, they began to run under the FTU banner with more pro-labour position. In October, Tsang Yok-sing, the founding Chairman of the DAB, was elected as the President of the Legislative Council, becoming the first LegCo President with party membership. His seat at the Executive Council was succeeded by vice-chairman Lau Kong-wah.
