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.

Embattled South Korean President Yoon Suk Yeol saw his approval rating sink to a record low of 11% on Friday ahead of a second impeachment motion over his short-lived declaration of martial law.

Prime Minister Han Duck-soo, who became South Korea's acting president after Yoon Suk Yeol's impeachment, is a career technocrat whose wide-ranging experience and reputation for rationality may not be enough to stem the country's deepening political crisis.

South Korea's opposition lawmakers have filed a motion to impeach the country's prime minister and acting leader Han Duck-soo, less than two weeks after parliament voted to impeach President Yoon Suk Yeol.

South Korea's opposition said Thursday it filed an impeachment motion against acting president Han Duck-soo, after he refused to appoint Constitutional Court judges to complete the process of removing his predecessor from office.
