South Korea's conservatives made another about-face on Saturday and reinstated their nominee, just hours after dropping him and reopening the nomination process as the divided party struggled for unity to challenge the liberal frontrunner in a presidential election four weeks away.

South Korea's conservatives made another about-face on Saturday and reinstated their presidential nominee, Kim Moon-soo, just hours after dropping him.

Han Duck-soo said he 'humbly accepts everything' and expressed hope that Kim would succeed in the election, which follows the impeachment of former president Yoon Suk Yeol.
