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.

South Korea’s parliament is set to vote Friday on impeaching Acting President Han Duck-soo, potentially deepening a political crisis that has rattled financial markets and disrupted diplomacy efforts.

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.
