In 2010, the Democratic Party decided to support the government's proposal of the political reform package to expand the numbers of legislative council members from 30 to 35 in Geographical Constituency and 30 to 35 of Functional Constituency by adopting the idea of the "Super-district Councillors" which will be voted across the territory after nominations by District Councillors. Younger members of the Democratic Party including Chan believed that such proposal could not provide any significant progress towards democratic development in local political agenda.
