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.

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

Finance Minister Choi Sang-mok is next in line to take on the mantle of the acting presidency, according to South Korean law.
