Albert Chan
In January 2010, Leong and other four lawmakers, Albert Chan, Tanya Chan, Leung Kwok-hung and Wong Yuk-man resigned their seats to force by-elections, in which they all stood, which they called on to be treated as a referendum to press the Chinese Central Government into allowing universal suffrage in Hong Kong. On 16 May 2010, he was re-elected as a lawmaker in the by-election.
