Protesters in South Korea demanded a re-run of the local elections due to ballot shortages. Around 10,000 citizens gathered at the SK Olympic Handball Stadium to protest the issue. On June 3, polling stations in parts of Seoul ran out of ballots, according to Bluesky. Some voters did not cast ballots due to ballot shortages. The head of the National Election Commission resigned due to the ballot shortage issue, as reported by CNA. The June 3 local elections included races for mayors, governors, heads of municipalities, and members of metropolitan and municipal councils, and coincided with parliamentary by-elections in constituencies where National Assembly seats became vacant between March 1, 2025, and April 30, 2026, according to Koreapro.org. Authorities in South Korea have not offered to hold a new vote, as reported by CNA. The ballot shortage incident is considered one of the most significant election administration crises in recent years in South Korea.
