TOKYO -- Conservative opposition leader Yoon Suk-yeol won the South Korean presidential election on March 9 with the narrowest lead ever, arousing speculation around the country about when the new government will launch investigations into alleged wrongdoing involving Yoon's contender from the progressive governing party Lee Jae-myung, and the outgoing President Moon Jae-in's government.
Yoon, the former prosecutor general, is seen as the symbol of opposition to Moon and his government. A former conservative presidential aide once said the first thing a new president does is investigate scandals of his or her predecessor and rivals.
