South Korean opposition leader Lee Jae-myung is projected to be the new president following a snap election on Tuesday, according to an exit poll by Korean broadcasters, in a vote held exactly six months after the country’s previous leader declared martial law and plunged the nation into chaos.

Both Lee and conservative Kim pledged change for a country deeply scarred by a shock martial law briefly imposed by former leader Yoon Suk Yeol.

The U.S. ally has been without a permanent leader since late last year, when Yoon Suk Yeol was impeached over his botched declaration of martial law.
