SEOUL, South Korea (AP) — South Korea’s opposition parties have submitted a motion to impeach President Yoon Suk Yeol, who is facing pressure to leave office hours after he ended a short-lived martial law that prompted troops to encircle parliament before lawmakers voted to lift it. Impeaching Yoon would require the support of two-thirds of parliament for the motion and then the backing of at least six Constitutional Court justices. The motion, submitted jointly by the main opposition Democratic Party and five smaller opposition parties, could be put to a vote as early as Friday. Yoon’s senior advisers and secretaries have offered to resign collectively and his Cabinet members, including the defense minister, also are facing calls to step down.
