South Korean President Yoon Suk Yeol's term in office has been dogged by personal scandals, an unyielding opposition and rifts within his own party, and a rapid fall from grace over his short-lived declaration of martial law last month.

South Korea's Yoon Suk Yeol rose from star prosecutor to the presidency in just a few years, but after a series of scandals and a bungled martial law decree, he's become the country's first-ever sitting president to be arrested.

Yonhap news agency says South Korean prosecutors have indicted the impeached President Yoon Suk Yeol over his imposition of martial law.
