The Sai Kung District Council is one of the fastest growing councils due to the rapid development of Tseung Kwan O new town in the late 1990s and early 2000s. Traditionally dominated by the rural forces, different political parties also established its presence in the urban area in the 1990s. The pro-Beijing Democratic Alliance for the Betterment of Hong Kong (DAB) doubled their seats from four to eight after absorbed the Hong Kong Progressive Alliance (HKPA) in 2005 and became the largest party in the council. The pro-Beijing Civil Force which has been in alliance with the New People's Party also has substantial presence in the district. The pro-democracy camp in the district was represented by the Democratic Party, until it lost half of its seats after the reformist faction led by Gary Fan quit the party and formed the Neo Democrats in 2010 over the disagreement on the constitutional reform proposal.
