Seoul: President Lee Jae Myung's approval rating slipped this week due to negative sentiment over ballot shortages that disrupted last week's local elections, a poll showed Monday.

According to Yonhap News Agency, in the poll commissioned by EKN newspaper and conducted by Realmeter, 55.2 percent said Lee was doing a good job, down 3.9 percentage points from a week earlier. The weekly survey was conducted on 2,013 people aged 18 and older from Monday to Friday last week, excluding Wednesday when the local elections were held.

The negative assessment climbed 4.2 percentage points to 41 percent. Realmeter said Lee's approval rating fell sharply after the local elections as criticism over the government's handling of the ballot paper shortage overlapped with the ruling Democratic Party (DP)'s failure to reclaim the Seoul mayoralty.

The sharp rise in the exchange rate later in the week further added to the negative sentiment, it said. Thousands of protesters have been rallying near a vote-counting facility in eastern Seoul for the fourth consecutive day, demanding a new election after more than a dozen polling stations in Seoul ran out of ballots during Wednesday's elections.

The survey had a margin of error of plus or minus 2.2 percentage points at a 95 percent confidence level.
