SEOUL, Aug. 26 (Yonhap) -- Rep. Lee Jun-seok, the leader of the minor opposition New Reform Party, announced his resignation Wednesday, taking responsibility for the party's significant defeat in the June 3 local elections.
During a press conference at the National Assembly, Lee stated that he had proposed reforms since the elections but did not receive sufficient internal support. He accepted full responsibility as party leader for failing to persuade others within the party.
The New Reform Party failed to win any of the 16 major mayoral and gubernatorial posts or the 14 parliamentary seats contested in the elections, securing only a single local council seat. The party's disarray was further compounded when one of its candidates, Jeong Yi-han, was arrested and indicted for allegedly staging an assault on himself in an apparent bid to garner voter sympathy.
Rep. Chun Ha-ram, the party's floor leader, is anticipated to serve as the interim party leader following Lee's departure.
