South Korea’s main opposition party has submitted a motion to impeach the country’s acting leader over his reluctance to fill three Constitutional Court vacancies ahead of the court’s review of rebell

South Korea's main opposition party said it will introduce a bill to impeach acting President Han Duck-soo on Thursday and hold a vote on Friday, a move that could deepen the country's constitutional crisis triggered by a short-lived martial law.

President Yoon Suk Yeol vowed to “fight to the end,” despite the opposition’s push to impeach him and his own party’s demand that he resign.

Yoon Suk Yeol defies another request for questioning over his failed attempt to impose martial law earlier this month.

President Yoon Suk Yeol listed numerous grievances against opposition lawmakers in an effort to justify his actions.

South Korean President Yoon Suk Yeol defended his decision to declare martial law in a televised address Thursday, claiming he did it to save democracy and vowing that he will "fight to the end."

South Korean police have questioned Prime Minister and Acting President Han Duck-soo as part of an investigation into the short-lived decision this month to impose martial law, an official at his office said on Friday.

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.

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.
