Lee Wing-tat
Tung Chee Hwa had long been an unpopular Chief Executive, especially after the controversies over the Article 23 of the Hong Kong Basic Law which caused more than 500,000 people to march on 1 July 2003. Tung claimed his health was deteriorating early in 2005 and suddenly resigned on 10 March 2005 which triggered the election of the Chief Executive. The Election Committee by-elections were held to update the membership of the Election Committee, filling in the vacancies in the Election Committee. The pro-democracy camp, with Democratic Party's chairman Lee Wing-tat as the Chief Executive candidate, attempted to get over 100 nominations from the Election Committee to enter the race to prevent Donald Tsang being elected uncontested.
