The ruling Saenuri party in South Korea has taken the majority of seats in parliamentary polls, winning 152 seats in the national assembly.
That gives the party 25 more than the Democratic United Party.
In a statement, President Lee Myung-bak said people had made "wise choices".
However, the Saenuri party struggled to hold on to its majority, shedding 13 seats.
DUP Secretary General Park Sun-sook has conceded defeat.
Polls closed at 6pm on Wednesday. Turnout was 54.3% compared to 46.1% four years ago, according to election officials.
The Saenuri (New Frontier Party) has 165 seats in the outgoing parliament, while the DUP had 89 seats.
