South Korea’s impeached president has denied that he ordered the military to drag lawmakers out of the National Assembly to prevent them from voting to reject his martial law decree last month, as he appeared for the first time before the Constitutional Court that will determine his fate.

South Korea’s impeached president, Yoon Suk Yeol, has been formally arrested, days after being apprehended at his presidential compound in Seoul.

Yoon Suk Yeol has faced South Korea's constitutional court for the first time, following last month's martial law saga.
