Three candidates vying for the ruling Democratic Party of Korea (DPK) leadership made their final pitches in a televised debate Wednesday, reiterating their commitment to working for the success of the Lee Jae Myung administration just days before the party picks a new leader.

The DPK is set to hold a national convention Monday to elect its new chair, who will play a key role in overseeing the nomination of candidates for the parliamentary elections in April 2028.

The race has largely been a competition between former Prime Minister Kim Min-seok, considered a key political ally of Lee, and former DPK leader Jung Chung-rae, who has faced criticism from some party members for focusing on appealing to his own hard-line supporters than on fully backing the president.

Kim vowed to unite the DPK and lead the party to secure a win in the next general elections.
