Oh Se-hoon's policies face a series of setbacks in the city council, with the Democratic Party holding 80 seats.

The Seoul City Council, dominated by the Democratic Party with 80 seats out of 118, has cut funding for several key projects of Mayor Oh Se-hoon's administration during preliminary reviews of supplementary budgets. The council's committees have slashed funds for initiatives such as the "Youth AI Growth Support" project, which aimed to provide 500,000 young people with AI usage rights and training, and the "Regional Night Market Creation and Operation" project.

The Democratic Party plans to reallocate the cut funds to restore the "Rights-Based Customized Public Jobs for People with Severe Disabilities" program. The city and council are likely to clash further over budget decisions, including funding for the Han River Bus project, during the upcoming review of the main budget.
