Ex-Defence Minister Kim Yong-hyun is likely to be the first to face indictment on the accusation of being a central figure in President Yoon's surprise martial law declaration on Dec. 3.

South Korea’s President Yoon Suk Yeol again declined to appear for questioning by investigators over his martial law declaration as the embattled leader seeks to first defend himself at an impeachment trial.

The Constitutional Court will decide whether to remove Yoon sometime in the next six months. If he is removed from office, a snap election will be called.
