S.Korean presidential chief of staff replaced

South Korea's presidential office has announced the replacement of the chief of staff to President Moon Jae-in amid a plunge in Moon's approval rating.

Outgoing Presidential Chief of Staff Noh Young-min revealed his own replacement at a news conference on Thursday. He had been seen as one of Moon's closest confidants.

Moon appointed former Minister of Science and ICT You Young-min to replace Noh.

Noh is due to resign to take responsibility for administrative chaos over prosecution reforms. Another senior presidential aide will also be replaced.

On Wednesday, the presidential office announced the nomination of former judge and current ruling party lawmaker Park Beom-kye as justice minister. He will succeed Choo Mi-ae, who has already announced her intention to resign as justice minister in the wake of a rift with Prosecutor General Yoon Seok-youl.

President Moon's approval rating has plunged due largely to antagonism between his administration, which proceeded with prosecution reforms, and the prosecutor general.

Analysts suggest Moon is putting new people into key posts in order to resolve the disarray and thereby stabilize his administration.
