The approval rating for the main opposition Democratic Party of Korea (DPK) rose to 44.2 percent, a poll showed Monday, exceeding support for the ruling party by more than the margin of error.

According to the survey conducted by Realmeter on 1,506 adults aged over 18 last week, support for the DPK gained 3.1 percentage points from the previous week, while the approval rating for the ruling People Power Party (PPP) fell 5.1 percentage points to 37.6 percent.

The survey has a margin of error of plus or minus 2.5 percentage points, with a confidence rate of 95 percent.

In the same survey, 46.3 percent of the respondents supported DPK leader Lee Jae-myung as a president in the future, followed by Labor Minister Kim Moon-soo at 18.9 percent and former PPP leader Han Dong-hoon at 6.9 percent.

If President Yoon Suk Yeol is ousted over his failed bid to impose martial law in December, the nation will be required to hold a snap presidential election within 60 days.

The survey showed that 55.1 percent support a change in power, while 39 percent are in favor of keeping the current conservative rule. (Yonhap)
