South Korea’s main opposition party picked a 36-year-old who has never served in parliament as its leader, turning to a reform advocate as it tries to reclaim the presidency next year.

The People Power Party voted Friday to select Lee Jun-seok as its leader, making the Harvard University graduate the youngest person to control the post for the main conservative bloc. He received 44% of the vote, ahead of the nearest contender, Na Kyung-won, a former parliamentary floor leader, who garnered 37%, according to the party.

Lee is seeking to appeal to younger people who feel the system favors the rich and connected, crucial swing voters who may decide who leads the country after President Moon Jae-in’s single five-year term ends in May. The new PPP chief has vowed to introduce "qualification tests” for would-be lawmakers, including testing their ability to use basic computer programs.
