Lee Jae-myung was sworn in as South Korea's president on Wednesday, just hours after his victory was certified in a snap election that brought an end to months of political turmoil in the country.

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.

South Korea's voters cast their ballots in a snap presidential election sparked by the impeachment of Yoon Suk Yeol.
