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

Kim Moon-soo's concession means Democratic Party candidate Lee Jae-myung has won the election to be South Korea's next leader. In a speech just concluded, Lee vowed to restore the country's economy and to make peace in the Korean peninsula.

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.
