President Moon Jae-in replaced some of his senior secretaries at Cheong Wa Dae on Friday, a move coupled with a major Cabinet shake-up to name a prime minister.

Former lawmaker Lee Cheol-hee was tapped as senior presidential secretary for political affairs, and Lee Tae-han, an audit official at the National Health Insurance Service, as senior secretary for social policy, Moon's office announced.

The president also named Park Kyung-mee, secretary for education policy, as new Cheong Wa Dae spokesperson.

Ki Mo-ran, professor of preventive medicine at the National Cancer Center, was appointed to oversee disease control and prevention affairs, a newly created post.

Earlier in the day, Cheong Wa Dae announced the pick of Kim Boo-kyum as new prime minister and the replacement of five ministers. (Yonhap)
