DP Poised for Strong Showing in June By-Elections

South Korea’s Democratic Party of Korea is expected to post a strong result in the June 3 parliamentary by-elections, with the party well positioned to win 10 or more seats across contests held alongside the country’s nationwide local elections. At least four National Assembly seats are set to be decided, and additional vacancies could still be added before election day, raising the stakes for both major parties.

A Democratic Party haul of 10 seats or more would give the opposition a clear boost and underscore its organizational strength as voters head to the polls. The final outcome will be closely watched as a measure of public sentiment midway through the political calendar, with results likely to shape the balance of momentum heading into the second half of 2026.
