South Korea's opposition was set to triumph in parliamentary elections on Wednesday, with exit polls suggesting it increased its majority in a major blow to President Yoon Suk-yeol.
The Democratic Party (DP) of Lee Jae-myung — survivor of a January knife attack and myriad scandals — and its satellites are forecast to win between 184 and 197 seats, up from 156 in the last parliament.
Yoon's People Power Party (PPP) and its satellite party were expected to have secured 85 to 99 seats, down from 114, the exit polls conducted by three major broadcasters indicated.
