The impeachment of South Korea’s acting President Han Duck-soo has plunged the country into further political turmoil, coming less than two weeks after lawmakers impeached President Yoon Suk Yeol.

South Korea's opposition-controlled National Assembly voted to impeach acting President Han Duck-soo, further deepening the country's political crisis.

The impeachment of Han Duck-soo, acting president since Yoon was impeached on Dec. 14 for declaring martial law, has thrown South Korea's once-vibrant democratic success story into uncharted territory.

South Korean lawmakers impeached acting president Han Duck-soo on Friday, sinking the country deeper into a political crisis triggered by his predecessor's martial law declaration that shocked the world.

Charges and counter-charges reverberate around South Korea’s impeached president, Yoon Suk-yeol. Add “resisting arrest” to the “insurrection” claimed by his foes. Then again, how about accusing the investigators of “trespassing” — and even staging an “insurrection” of their own — in Korea’s version of “Catch Me if You Can”?

South Korea’s main opposition party said it will start impeachment proceedings against Prime Minister and Acting President Han Duck-soo.

South Korea's main opposition party introduced a bill to impeach acting President Han Duck-soo on Thursday, a day before it plans to seek a vote on the move, which could deepen a constitutional crisis triggered by a short-lived 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.
