Democratic Party's Lee Jae-myung set to be South Korea's new president, exit polls show

Vote counting for South Korea's presidential election is underway, after months of political turmoil. The Democratic Party's Lee Jae-myung is projected to win by a landslide, with a joint exit poll by major broadcasters showing him with about 52% of the vote. Millions turned up in force to over 14,200 polling booths, with turnout rising past 77% and hitting a record high as of 7pm local time. Young voters are likely to be a decisive force in shaping South Korea’s political future. Those in their 20s and 30s have formed a powerful bloc this election, energised by last December's martial law crisis. Lim Yun Suk and Grace Shin report.
