SEOUL—South Korea’s legislature voted to impeach acting President Han Duck-soo on Friday after he declined to make judicial appointments needed to advance the impeachment of his predecessor, extending the political upheaval that began with a short-lived martial law declaration earlier this month.

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

South Korea has voted to impeach its acting president Han Duck-soo, two weeks after parliament voted to impeach its President Yoon Suk Yeol. Some 192 lawmakers voted for his impeachment, more than the 151 votes needed for it to succeed.
