South Korea’s former opposition leader Lee Jae-myung still remains the frontrunner for now in a presidential election that will struggle to heal the political divide in a nation racked by leadership chaos in recent months.

Democratic Party nominee Lee Jae-myung will be retried on electoral violation charges, while the acting president has resigned and is expected to enter the race.

South Korea's Supreme Court said it will rule on Thursday in a criminal case that could determine whether the frontrunner for the June 3 snap election, former opposition party leader Lee Jae-myung, can run for president.
