Rho Tae-ak resigned as head of South Korea's National Election Commission on June 5 after ballot shortages affected 50 of approximately 14,300 polling stations and caused delays at 22 others during the June 3 local elections. Protesters maintained a 35-hour blockade at one Seoul station that was cleared by riot police. President Lee Jae Myung's Democratic Party won most races but lost the Seoul mayoral contest in the first nationwide vote since his inauguration.
