UNITED Democrat Lam Wing-yin has been elected to the Regional Council with 4,670 votes after beating six other candidates in the scramble for the seat vacated by convicted councillor Gilbert Leung Kam-ho.
Mr Lam's victory marked the end of the conservatives' domination in the Sai Kung constituency.
It also strengthened the liberals' influence in Regco by bringing the number of United Democrats to six.
The pro-China Democratic Alliance for the Betterment of Hong Kong (DAB) was beaten into second place in Sunday's poll, with its candidate, Cheung Hon-tin, getting 4,016 votes.
Both Mr Lam and Mr Cheung, the first candidate fielded by the DAB since its inception last year, finished more than 1,300 votes ahead of the other candidates.
The vice-chairman of the Association for Democracy and People's Livelihood, Law Cheung-kwok, came third with 2,657 votes - another defeat for him after the 1991 Legislative Council election.
