Impeached South Korean leader Yoon Suk Yeol is due to attend the first hearing on Monday of his criminal trial to face charges that he led an insurrection when he declared martial law late last year and plunged the country into months of turmoil.

A South Korean court removed President Yoon Suk Yeol from office over his ill-fated martial law declaration, paving the way for a presidential race to end a leadership vacuum that has gripped the nation for months.
