Park Chan-dae, floor leader of South Korea’s main opposition Democratic Party (DP), announced on Thursday that the party intends to launch impeachment proceedings against Acting President Choi Sang-mok. Speaking to reporters, Park stated that Choi’s failure to appoint Constitutional Court nominee Ma Eun-hyuk is unconstitutional. He added that the specific timing and procedure for the impeachment will be determined after further consultation.

Park claimed that National Assembly Speaker Woo Won-shik supported the move, but a representative from the speaker’s office later stated that Woo had not committed to supporting impeachment proceedings at this time.
