South Korea's third acting president in five months, Lee Ju-ho, said on Friday he will ensure stable government ahead of a June 3 presidential election, following the quick-fire resignations of the prime minister and finance minister.

Hours earlier, Education Minister Lee took over as acting leader, thrusting him into the job of shepherding Asia's fourth-largest economy through the political turmoil triggered by a martial law attempt last year by ousted President Yoon Suk Yeol and the impact of sweeping U.S. tariffs.

Lee pledged to work closely with the Cabinet and opposition-led parliament which impeached Yoon in December, and to try to stabilize the government.
