South Korea’s opposition Democratic Party of Korea has named Lee Jae-myung as its candidate for the snap presidential election set for June 3.

“I am not only the candidate of the Democratic Party, but of all people who yearn for the end of insurrection, the overcoming of crisis, and the pursuit of unity and happiness,” Lee said in his acceptance speech after securing the nomination on Sunday.

Lee won his party’s nomination with nearly 90 percent of the vote during the primary, outpacing two other contenders.

A progressive leader advocating for greater economic equality and improved relations with North Korea, Lee is now the frontrunner to succeed President Yoon Suk-yeol, who was ousted following the attempted imposition of martial law late last year.

The 60-year-old former leader of the main opposition party led the impeachment process against Yoon over the martial law order in December.
