South Korea's opposition party has threatened to impeach acting president Han Duck Soo should he fail to proclaim a law to launch a special counsel investigation into Yoon Suk Yeol's botched attempt at imposition of martial law.
Mr Yeol was impeached on 14 December through a second vote in parliament over his attempt to impose martial law earlier this month, a move that threw the nation into chaos and split his party. Prime minister Han has since taken over as Yoon's presidential powers remain suspended.
