South Korea Ruling Party Grapples With Seoul Mayor Nomination Ahead of June Elections
The leader of South Korea’s ruling People Power Party, Jang Dong-hyuk, said that “nominations are the lifeblood of fairness” as Seoul’s mayoral nomination process heads toward the June local elections with questions unresolved. He noted that Seoul Mayor Oh Se-hoon did not apply for the party’s additional candidate recruitment by the 6 p.m. deadline after Oh earlier signaled a vow to sever ties.
Oh Se-hoon, who remains the PPP’s candidate for Seoul mayor, had not filed for the extra round of nominations by the deadline, according to party officials. He had previously issued a vow to sever ties, and the party said there were no signs that he was moving into an active phase of the nomination process.

Lee Jeong-hyeon, the chair of the party’s nomination management committee, told reporters he intended to resign, a development that has complicated the leadership’s efforts to manage the Seoul race. Jang said he attempted to contact Lee at about 9:10 a.m., but the phone was off, and he would meet Lee as soon as contact could be established.
A party insider explained that local elections typically attract many candidates, and the party fears public disputes over nominations could undermine the process and dilute the credibility of the nomination itself.
Concerning Oh’s push for an “Innovative Election Strategy Committee,” Jang questioned what it would mean if it implied a demand for the party leader’s resignation, saying the concept of such a claim should be clarified before any acceptance. He cautioned against moves that could blur the purpose of the party’s nomination process.

The official stressed that it remains unclear whether Lee’s planned resignation would derail the nomination process, but acknowledged there is disappointment that the lawmakers’ caucus had only barely united behind a consensus, and that the party must clearly define its aims moving forward.
Why this matters beyond Korea: Seoul, as the capital and a major global tech and business hub, influences national policy directions on urban innovation, infrastructure, digital governance, and regulatory environments. A protracted internal dispute within the ruling party ahead of June’s local elections could signal policy volatility that affects foreign investment, technology partnerships, and supply chains involving U.S. companies with interests in Korea or the broader Asia-Pacific region. For U.S. readers, Seoul’s leadership style and policy outcomes can shape the business climate, regional security coordination, and the pace of digital initiatives that increasingly intersect with American firms and markets.
