Prime Minister Kim Min-seok said on the 5th that, if necessary, "the National Assembly should conduct a parliamentary investigation or appoint a special prosecutor to clearly determine the cause and improve the system regarding the shortage of election commission ballot papers."
In a post on Facebook the same day, Kim said the "shortage of election commission ballot papers is something that cannot possibly be overlooked" and called it "a serious challenge to K-democracy."
He added that "through all means and measures, including an investigation, I have ordered the full truth of this incident to be uncovered and severe accountability to be pursued."
During the June 3 local elections' main vote, ballot papers ran short at more than 10 polling stations nationwide, halting voting.
