Thousands of South Koreans were demanding a rerun of local elections as they protested into the wee hours of Sunday over ballot paper shortages that disrupted this week’s vote.

Wednesday’s election was the first nationwide vote since President Lee Jae Myung took office following conservative Yoon Suk Yeol’s ouster over his brief martial law declaration in late 2024.

Lee’s ruling, liberal Democratic Party won most races but failed to flip the key Seoul mayoral seat.
