Seoul: President Lee Jae Myung's approval rating has experienced a slight decline, following two weeks of growth, as revealed by a recent survey. The dip comes in the wake of a contentious decision by the prosecution not to appeal a significant development corruption case tied to him.

According to Yonhap News Agency, the survey conducted by Realmeter, commissioned by a local news outlet, indicates that 54.5 percent of respondents positively assessed Lee's job performance, marking a decrease of 2.2 percentage points from the previous week. Concurrently, the negative assessment of Lee rose by 2.5 percentage points to 41.2 percent.

Realmeter suggests that the decline in approval is linked to growing public frustration over the escalating political disputes between rival parties concerning the prosecution's decision not to pursue an appeal in the case. The corruption case in question involves allegations that a select few unqualified asset management companies, including Hwacheon Daeyu, were permitted to earn substantial investment returns from a real estate development project in Seongnam's Daejang-dong district in 2015, during Lee's tenure as mayor.

Critics and opposition lawmakers have voiced suspicions that the prosecution's decision to forego an appeal by the November 7 deadline may have been swayed by governmental interference. The survey, which gathered responses from 2,510 adults over the course of last week, has a margin of error of plus or minus 2 percentage points and a confidence level of 95 percent.

In a separate survey by the same pollster, conducted with 1,006 individuals aged 18 and over on Thursday and Friday, the ruling Democratic Party's approval rating saw a slight increase of 0.2 percentage points to 46.7 percent. Meanwhile, support for the main opposition People Power Party declined by 0.6 percentage points to 34.2 percent. This poll has a margin of error of plus or minus 3.1 percentage points, maintaining a confidence level of 95 percent.
