South Korea's impeached President Yoon Suk Yeol has been charged with insurrection after he attempted to declare martial law in December. His ill-fated attempt to impose military rule plunged the country into an unprecedented political crisis and he becomes the first sitting president in South Korean history to be charged with a crime.

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.

The charges are unprecedented for a South Korean president, and if convicted, Yoon Suk Yeol could face years in prison for his shock martial-law decree, which sought to ban political and parliamentary activity and control the media.
