By Joyce Lee SEOUL (Reuters) -South Korea's Constitutional Court will hold its first hearing on Friday in the case of President Yoon Suk Yeol, after parliament impeached him over his short-lived martial law decree on Dec.

South Korea’s main opposition party said Tuesday it will seek to impeach acting leader Han Duck-soo after he missed an opposition-set deadline to approve independent investigations into impeached President Yoon Suk Yeol and his wife.

South Korea’s main liberal opposition party said Tuesday it will seek to impeach acting leader Han Duck-soo, as Seoul grapples with the turmoil set off when impeached President Yoon Suk Yeol made a short-lived declaration of martial law.

South Korea's main opposition party threatened on Monday to impeach acting president Han Duck-soo if he failed to approve legislation to launch a special counsel investigation into President Yoon Suk Yeol's failed bid to impose martial law.

South Korea’s acting leader says he will veto a spate of contentious bills sponsored by the main opposition party, deepening political strife in the wake of parliament’s impeachment of President Yoon Suk Yeol.
