2010 Hong Kong by-elections

The 2010 Hong Kong Legislative Council by-election was an election held on 16 May 2010 in Hong Kong for all five geographical constituencies of the Legislative Council (LegCo), triggered by the resignation of five pan-democrat Legislative Councillors in January of the same year. Discussions among the pan-democrats commenced in July 2009 for five legislators to resign to force a territory-wide by-election.
