Seoul Mayor Oh Se-hoon announced on the 12th that he would participate in the upcoming mayoral election but did not submit his application for candidacy before the deadline set by the People's Power party, indicating deep discontent with the current state of the party. Oh has been vocal about needing significant changes within the party and has publicly demanded the resignation from frontline duties of Jang Dong-hyuk, emphasizing that continuing in the current situation would not yield any positive outcome for the election. He expressed that the timing was not right to register for candidacy without real change, as the party's poll numbers were significantly lagging compared to their main opponents, the Democratic Party.

Furthermore, during a party meeting, Jang sought to pause discussions on disciplinary actions prior to the local elections, reflecting a divide within the party. Despite his attempts to broker a sense of unity and mitigate tensions, Oh and his supporters have been insistent that the party's transformation is imperative for any serious electoral contest. Oh's insistence on an early launch of an innovative election campaign team, excluding Jang, underlines the ongoing power struggles within the party and points to the necessity for new faces that are distinct from the current leadership, which they believe could revitalize their electoral prospects in the capital region.
