2010 Five Constituencies Referendum

On 29 January 2010, Chan, together with four other lawmakers (two from Civic Party, two from LSD) Alan Leong, Tanya Chan, Leung Kwok-hung and Wong Yuk-man, resigned their seats in the Legislative Council. They intended that the popular vote in the by-elections triggered by their resignations would act as a de facto referendum on electoral reform, pressing the PRC Government into allowing universal suffrage in Hong Kong in compliance with Hong Kong's constitution, the Basic Law.^[2] On 16 May 2010, he was re-elected as a lawmaker in the by-election.^[3]

People Power

In January 2011, Chan and fellow legislator Wong Yuk-man resigned from the League of Social Democrats over differences with the leadership over what stance to take towards the Democratic Party in the discussions over Hong Kong's political development. The move left the party and its remaining legislator, Leung Kwok-hung ('Long Hair') in a difficult position. They also said that factional fighting within the party has become so hostile that it was beyond their ability to rectify the situation.^[4]

With Wong, he went on to launch People Power, under which name he continues to sit in Legco. In 2011 regional elections, he went against Tuen Mun Lok tsui Constituency's candidate Albert Ho Chun-yan, the then-chairman of Democratic Party. However, he was defeated.^{[citation needed]} In 2012 legislative elections, Chan was reelected for a seventh time. He chose to make way for the youngster in the 2016 Legislative Council election, standing as a second candidate of Wong Ho-ming of its ally League of Social Democrats under the banner of "radical democrats". The list received 28,529 votes and failed to retain the seat.^{[citation needed]}
