SEOUL, South Korea (AP) — Lee Jae-myung, who rose from childhood poverty to become South Korea’s leading liberal politician vowing to fight inequality and corruption, will become the country’s next president on Wednesday after an election that closed one of the most turbulent chapters in the young democracy.

Lee, 60, the candidate of the liberal opposition Democratic Party, is taking office for a full, single five-year term, succeeding Yoon Suk Yeol, a conservative who was felled over his stunning yet brief imposition of martial law in December.
