People Power–League of Social Democrats

The People Power–League of Social Democrats, are the two radical democratic parties set up an electoral alliance for the 2016 Hong Kong Legislative Council election under the name of “progressive democrats”. It fielded a total of nine candidates to contest Legislative Council seats in the five geographical constituencies, in which two of the three incumbents were returned.

The League of Social Democrats (LSD) was established in 2006 with the social democratic and street action agenda. In 2008 Legislative Council election, three candidates, chairman Wong Yuk-man, Albert Chan Wai-yip and Leung Kwok-hung each won a seat and received 10 percent of the popular vote. In 2009, the League proposed a "Five Constituencies Resignation" to trigger a territory-wide by-election which could be seen as a referendum on the government's constitutional reform proposal. While it was joined by the professional-oriented pro-democratic Civic Party, it was opposed by the flagship Democratic Party. The by-election failed to realise a massive turnout and caused the infighting within in the pro-democratic camp as the Democrats negotiated with the Beijing government in secret.

In 2011, Wong Yuk-man and Albert Chan Wai-yip split away from the LSD over the interpersonal disputes and the stances on the spinning the Democratic Party in the 2011 District Council election after the 2012 constitutional reform package. The then chairman Andrew To Kwan-hang and his faction insisted a tolerant stance toward the Democratic Party while Wong strongly disagreed. About two hundred of their supporters joined Wong, leaving the LSD in disarray. They later formed the People Power with Power Voters supported by Stephen Shiu Yeuk-yuen, the owner of the Hong Kong Reporter, the re-grouped Frontier and the two pro-Taiwan organisations China Youth Organization and Democratic Alliance. In the 2012 Legislative Council election, the two parties won nearly 15 percent of the popular votes. Leung Kwok-hung and Raymond Chan Chi-chuen both won a seat in New Territories East while Wong Yeung-tat posed a challenge to Andrew To Kwan-hang in Kowloon East and eventually both lost to the pro-Beijing Paul Tse Wai-chun.
