A former chief of staff to now-jailed President Yoon Suk Yeol appeared at a court Friday for a hearing on his potential arrest over alleged irregularities in the 2022 relocation of the presidential residence.

Kim Dae-ki is accused of illegally diverting 2.8 billion won ($1.8 million) from the interior ministry's budget to pay an interior design company for the renovation of the presidential residence during its relocation from Cheong Wa Dae to the central Seoul district of Yongsan.

The company, 21 Gram, is suspected of having won the project despite being unqualified, due to its ties with Yoon's wife, Kim Keon Hee.

The former presidential official told reporters that he would "faithfully" explain his position as he arrived at the Seoul Central District Court to attend his arrest warrant hearing.
