A prolonged period of uncertainty over the fate of impeached South Korean President Yoon Suk Yeol and the botched attempt to arrest him are giving oxygen to his backers and reviving support for his troubled party.

South Korea's suspended President Yoon Suk Yeol ignored the objections of key cabinet ministers before his failed martial law bid last month, according to a prosecutors' report seen by AFP on Sunday.

South Korean investigators trying to arrest suspended President Yoon Suk Yeol have less than 24 hours before their warrant expires Monday, with the embattled leader holed out in his residence surrounded by loyal security forces.
