South Korea's acting President Choi Sang-mok said on Tuesday he would immediately move to fill vacancies on the Constitutional Court in a effort to restore stability after the impeachment of two of his predecessors this month triggered political turmoil.

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.

Han has been the caretaker leader after President Yoon Suk Yeol was impeached by the assembly over his short-lived imposition of martial law earlier this month.

The plane crash is the first major test for South Korea’s acting president, Choi Sang-mok, who had been appointed the interim leader only on Friday, as the country grapples with a political crisis at the highest levels.
