South Korea's acting president faces an impeachment vote on Friday, intensifying a political crisis as the Constitutional Court meets for its first hearing on suspended President Yoon Suk Yeol's short-lived martial law declared on Dec.

As the president awaits an impeachment trial, the country’s interim leader may, too, be ousted. The currency has plunged as the crisis has deepened.

The Democratic Party has criticised Han for delaying the appointment of three justices to the Constitutional court, claiming he exceeded his authority as acting leader.
