South Korea’s former Prime Minister Han Duck-soo says he will run in next month’s presidential election and would seek to lessen the powers of the office and ease strife-ridden domestic politics if he wins.

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 snap presidential election, following the quick-fire resignations of the prime minister and finance minister.

Prime Minister Han Duck-soo has been mulling whether to run for election, while the main opposition candidate and front-runner suffered a setback in court.
