SEOUL, South Korea — South Korea’s liberal opposition parties were expected to win a landslide victory in Wednesday’s parliamentary election, initial exit polls suggested, a result that if confirmed would make conservative President Yoon Suk Yeol a lame duck for his remaining three years in office. [time-brightcove not-tgx=”true”] The joint exit polls by South Korea’s three major TV stations – KBS, MBC and SBS – showed the main opposition Democratic Party and its satellite party were forecast to win combined 178-197 seats in the 300-member National Assembly.
