Yoon Suk Yeol was summoned for questioning over attempt to impose martial law earlier this month

South Korea’s impeached president, Yoon Suk Yeol, failed to appear before the country’s corruption watchdog on Wednesday, it said, after he was summoned for questioning over his attempt to impose martial law.

Yoon was stripped of his duties by parliament over the weekend after his short-lived 3 December martial law declaration, which plunged the country into its worst political turmoil in decades.
