South Korea's parliament began a session on Friday where a vote to impeach acting President Han Duck-soo over short-lived martial law is scheduled, as the Constitutional Court said it would swiftly decide suspended President Yoon Suk Yeol's fate.

South Korea’s opposition-controlled National Assembly has voted to impeach the country’s acting leader, Han Duck-soo.

Counting for the impeachment was delayed as ruling People's Power Party lawmakers protested after the National Assembly speaker said only a simple majority was needed in the 300-member parliament.
