Opposition leader Lee Jae-myung was sworn in as South Korea’s next president on Wednesday following a dramatic snap election six months after the country’s previous leader declared martial law and plunged the nation into chaos.

Pre-election surveys suggest Yoon Suk Yeol's liberal rival, Lee Jae-myung, appears headed for an easy win, riding a wave of public frustration in the wake of Yoon's martial law debacle.

South Korea's liberal party candidate Lee Jae-myung is projected to win Tuesday's snap presidential election by wide margins, according to exit polls.
