Ruling party’s boycott of impeachment vote at weekend was an ‘unconstitutional act of a second insurrection’, says opposition Democratic party

South Korea’s opposition has accused the ruling party of staging a “second coup” by refusing to impeach the president, Yoon Suk Yeol, over his botched declaration of martial law last week.

Yoon’s attempt to end civilian rule on Tuesday lasted just six hours after lawmakers scuffled with soldiers in the parliament building before voting to lift the order.
