SEOUL, South Korea — South Korea’s prime minister and senior presidential officials offered to resign en masse Thursday after their ruling party suffered a crushing defeat in parliamentary elections in a huge blow to conservative President Yoon Suk Yeol.
The results of Wednesday’s elections mean the liberal opposition forces will prolong their control of parliament until after Yoon completes his single five-year term in 2027. That will most likely set back Yoon’s domestic agenda and weaken his grip on the ruling party as he faces the opposition’s intensifying political offensive during his remaining three years in office, experts say.
Prime Minister Han Duck-soo and all senior presidential advisers to Yoon, except those in charge of security issues, submitted their resignations, according to Yoon’s office. It did not immediately say whether Yoon accepted their resignations.
Executive power in South Korea is heavily concentrated in the president, but the prime minister is the No. 2 official and leads the country if the president becomes incapacitated.
Yoon said he will “humbly uphold” the public sentiments reflected in the election outcome and focus on improving people’s economic situations and on reforming state affairs, Yoon’s presidential chief of staff, Lee Kwan-seop, said in a televised briefing.
In a separate news conference, ruling People Power Party leader Han Dong-hoon said he would step down as well to take responsibility for the election defeat.
“I apologize to the people on behalf of our party, which wasn’t good enough to win the people’s choices,” he said.
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.
Yoon’s ruling People Power Party and its satellite party were projected to have obtained 108 seats.
The final official results were expected later Thursday.
Regardless of the results, Yoon will stay in power and his major foreign policies will most likely be unchanged. But Wednesday’s elections were widely seen as a midterm confidence vote on Yoon, a former top prosecutor who took office in 2022.
Yoon has pushed hard to boost cooperation with the United States and Japan as a way to address a mix of tough security and economic challenges. But he has been grappling with low approval ratings at home and a liberal opposition-controlled National Assembly that has limited his major policy platforms that require legislative approvals.
Hong Sung Gul, a public administration expert at Seoul’s Kookmin University, said Yoon will most likely find it more difficult to implement business-friendly policies and tax reforms, as the opposition parties are likely to aggressively flex their legislative muscles.
“When it comes to policies, important ones like tax system reforms require legislation. I think there is a high possibility for the opposition parties to put a brake on Yoon’s such policy agendas,” Hong said.
Yoon’s critics have accused him of failing to resolve livelihood issues such as soaring prices, refusing to quickly fire some top officials implicated in scandals, and lacking efforts to communicate with opposition leaders for policy coordination.
Earlier this year, Yoon briefly enjoyed rising approval ratings over his strong push to drastically increase the number of medical students despite vehement protests by incumbent doctors. But the doctors’ walkouts eventually left Yoon facing growing calls to find a compromise, with patients and others experiencing delays of surgeries and other inconveniences.
The rival parties’ campaigning ahead of Wednesday’s elections deepened South Korea’s already serious conservative-liberal divide as they exchanged toxic rhetoric and mudslinging.
Democratic Party leader Lee Jae-myung lost the 2022 presidential election to Yoon in the country’s most closely fought presidential contest. During the 2022 race, Yoon and Lee and their supporters spent months demonizing each other.
Lee is eyeing another presidential bid. His main potential conservative rival is Han, who also served as Yoon’s justice minister. Lee faces an array of corruption investigations that he argues are politically motivated and pushed by Yoon’s government.
“The results of the parliamentary elections are not the victory by the Democratic Party, but the great victory by our people,” Lee said Thursday. “Now, the elections are over. Both the ruling and opposition political parties must pull together all their strength to resolve economic and public livelihood problems.”
