President Lee Jae Myung's approval rating dropped to 46.3 percent this week, a poll showed Monday, marking its second straight weekly decline.

In the poll conducted by Realmeter and commissioned by the EKN newspaper, the positive assessment of Lee's job performance fell 2.1 percentage points from a week before, while his negative assessment rose 1.5 percentage points to 49.5 percent.

Realmeter attributed the decline to a controversy surrounding the sale of Lee's apartment and his remarks suggesting higher property holding taxes, as well as a sharp drop in the stock market.

Lee recently faced backlash after records showed that the buyers of his apartment in Seongnam, south of Seoul, paid only part of the purchase price upfront, with Lee and his wife effectively loaning the unpaid portion to the buyers until the balance is paid.
