Yoon Suk Yeol, South Korea’s since-impeached president, had been planning for months to impose martial law and target political opponents, according to accounts.

The vote was the second major impeachment in two weeks after President Yoon’s ill-fated martial law bid set off turmoil. The country’s currency has plunged.

South Korea’s President Yoon Suk Yeol again declined to appear for questioning by investigators over his martial law declaration as the embattled leader seeks to first defend himself at an impeachment trial.
