South Korea's ruling PPP in turmoil as Seoul mayor pushes reform
Widening tensions in South Korea’s political scene burst into the national spotlight as a so-called “prosecution withdrawal trade” controversy intensifies. Seoul Mayor Oh Se-hoon has pressed for party reform and has boycotted nominating applications, while Lee Jeong-hyun, the head of the People Power Party’s (PPP) nomination committee, abruptly resigned.
The opposition Democratic Party said it would file a defamation complaint against Jang In-su over allegations fueling the dispute, but critics questioned why the filing came two days after the concerns were raised and why the operator of a YouTube channel run by Kim Eo-jun was left off the list. Park Chan-dae, a Democratic Party lawmaker, acknowledged some public sentiment may differ, but said the party would proceed after legal review, as cited in a party briefing.
Inside the PPP, officials argued that the issue is linked to how the party handles media and information. They told YTN that while a YTN anchor’s remarks were problematic, suing the broadcaster did not appear to be the aim; the party instead pointed to potential regulatory scrutiny by media overseers given Kim Eo-jun News Factory’s registered status as a media entity.
The PPP’s leadership also signaled tougher responses, suggesting that because Kim Eo-jun News Factory is registered as a media outlet, it could face sanctions from the Korea Communications Commission’s broadcasting and communications ethics body. Kim Eo-jun responded on air that prosecutions could be advantageous, arguing the charges would show there was no pre-coordination of the scoop with Jang In-su.
In a separate development, the PPP’s stance hardened around Justice Minister Jeong Seong-ho, with calls for an impeachment process as part of broader political maneuvering. The party framed the move as a necessary step in their broader investigations and political accountability, a stance that underscored the febrile atmosphere inside the ruling camp.
Lee Jeong-hyun’s sudden resignation as nomination committee chairman followed reports of deep divisions over primary procedures. Secretary-General Jeong Hee-yong said the party would seek to persuade him to return, indicating a potential effort to bridge internal rifts ahead of local elections.
Oh Se-hoon’s push for party renewal is unfolding as candidate registration for local races looms, with the mayor arguing that he cannot stand as a PPP candidate without a refreshed leadership slate. Within the party, debates raged between a faction urging rapid reforms to maximize electoral victory and others pushing for alternative strategies, including courting senior figures such as Ahn Cheol-soo.
The dispute matters beyond Korea because Seoul’s leadership shapes the city’s business climate, technology policy, housing and urban development, and Korea’s broader alliance with the United States. Any shift in Seoul’s governance could affect foreign investment, supply chains in key sectors like semiconductors and tech, and regulatory signals that impact U.S. companies operating in Korea. The episode also highlights how media, political factions, and rule-of-law questions intersect in a democracy that hosts one of Washington’s closest Asian allies.
