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.

South Korea's new liberal President Lee Jae-myung began his term on Wednesday, vowing to raise the country from the turmoil of a martial law crisis and revive an economy reeling from slowing growth and the threat of global protectionism.
