South Korea’s president defended his martial law decree as an act of governance and denied rebellion charges, vowing to 'fight to the end' in the face of attempts to impeach him and intensifying investigations.

Shortly before the second impeachment vote of South Korean President Yoon Suk Yeol, the chairman of the ruling party has said he's in favour of removing Yoon - a change from his previous position. But there are no signs that the president is willing to go quietly.
