South Korea’s president has apologised for a string of controversies surrounding his wife that included allegedly accepting a luxury Dior handbag and stock manipulation.

Addressing the nation on television, Yoon Suk Yeol said his wife, Kim Keon Hee, should have conducted herself better, but her portrayal had been excessively “demonised”, adding that some of the claims against her were “exaggerated”.

The president said he would set up an office to oversee the first lady’s official duties, but rejected a call for an investigation into her activities.

Yoon’s apology came as he tries to reverse a dip in his popularity among the South Korean public, linked to the controversies surrounding his wife.

Late in 2023, left-wing YouTube channel Voice of Seoul published a video that purportedly showed Mrs 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 Mr Yoon’s conservative People Power Party, at the time labelled the president’s “shameless attitude” as “hopeless”.

The scandal also caused rifts within Mr 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, Mr Yoon vetoed a bill calling for his wife to be investigated over those allegations.
