SOUTH KOREA’S prime minister and senior presidential officials offered to resign en masse today after their ruling party suffered a crushing defeat in parliamentary elections in a huge blow to right-wing President Yoon Suk Yeol.

With most of the votes counted, the main opposition Democratic Party and its satellite party appeared to have won a combined 175 seats in the 300-member National Assembly. 

Another small liberal opposition party was expected to win 12 seats under a proportional representation system, according to South Korean media tallies.
