South Korea will hold a snap presidential election June 3 to choose Yoon Suk Yeol’s successor after the conservative was ousted over his imposition of martial law late last year.

President Yoon’s brief martial law declaration and subsequent impeachment trial have deeply divided South Korea, a key U.S. ally.

With his ouster, a presidential election is required to take place within 60 days, according to the South Korea's constitution.
