Kim Sang-ho, head of the Chun-chu Office at the Blue House, expressed his intention to resign. Kim, who is from a journalist background and has a long relationship with President Lee Jae-myung, was appointed as the first head of the Chun-chu Office after last year's presidential election and served for about a year. If his resignation is accepted, further restructuring of the Blue House staff is expected. In particular, Kim is known to be a key figure in the 'Seongnam·Gyeonggi line', and his departure could lead to a wider range of secretary replacements.
