The 2016 Election Committee subsector elections were held on 11 December 2016 for 1,034 of the 1,200 members of the Election Committee (EC) which is responsible for electing the Chief Executive of Hong Kong (CE) in the 2017 election. Although incumbent Chief Executive Leung Chun-ying announced, two days before the election, that he would not be standing, the pro-democrats, whose campaign theme was opposition to Leung serving a second term, won a record quarter of the seats on the EC under the banner of "Democrats 300+" on a nearly 20 per cent surge in turnout over 2011.
