Late in 2023, left-wing YouTube channel Voice of Seoul published a video that purportedly showed Kim accepting a 3m won ($2,200; £1,800) Dior bag from a pastor, who filmed the exchange in September 2022 using a camera concealed in his watch.
In February, Yoon said that the footage was leaked as a “political manoeuvre”, and did not apologise.
South Korea’s Democratic Party, the opposition to Yoon’s conservative People Power Party, at the time labelled the president’s “shameless attitude” as “hopeless”.
The scandal also caused rifts within Yoon’s party, with one leader comparing Ms Kim with Marie Antoinette, the queen of France notorious for her extravagant lifestyle.
The opposition party has also long accused the first lady of being involved in stock price manipulation. Earlier in the year, Yoon vetoed a bill calling for his wife to be investigated over those allegations.
