Jasper Tsang
Ma was formerly the Secretary General of the DAB, and became the Chairman of the DAB in December 2003 when Jasper Tsang resigned following the poor performance of the party in the November 2003 District Council elections; in those elections, the pro-democratic camp won 150 seats, while DAB secured only 62 seats out of the 205 DAB candidates fielded. Ma was re-elected leader on 25 April 2007.
