The pro-establishment Democratic Alliance for the Betterment and Progress of Hong Kong remains the largest party in Legco, with its vote-splitting tactics clinching 13 seats, compared to 10 in 2008.
The DAB grabbed nine seats out of 35 geographical constituency seats and one super seat in the new district council (second) functional constituency for its vice chairwoman Starry Lee Wai-king.
Three DAB candidates won uncontested.
DAB chairman Tam Yiu-chung admitted the party gained more seats in geographical constituencies thanks to its vote- splitting strategy.
But Tam was disappointed that party vice chairman Lau Kong- wah, known as the city's "king of votes," lost in the super seats showdown.
"We are heartbroken that Lau lost the race in the super seats constituency."
Lau admitted the result was a crushing disappointment.
"However, when we gear up for election, we are already prepared for loss."
Earlier, Federation of Trade Unions' honorary president Cheng Yiu-tong criticized some pro- establishment parties, notably the DAB, for asking FTU supporters to cast their ballots for DAB candidates.
In reply, Tam said Cheng did not clearly understand the situation and stressed that such incidents will not undermine relations between the DAB and FTU.
