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

SEOUL, South Korea (AP) — 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 vowed on Tuesday to impeach acting president Han Duck-soo but reversed an earlier plan and decided to wait until later in the week, party officials said, as the risk of further political uncertainty heightened.
