The ruling and opposition parties clashed over real estate policies and tax revision bills during the parliamentary interpellation session. The Democratic Party of Korea criticized Seoul Mayor Oh Se-hoon, saying that the city was hindering housing supply, while the People Power Party argued that the government's tax revision bill on real estate was a fine that regulated residential and relocation freedom. Deputy Prime Minister and Minister of Economy and Finance Koo Yun-cheol refuted that the tax revision bill was not punitive and was an incentive to create a housing market centered on residence. The controversy over the participation of a staff member from the Prime Minister's Office in a press conference by independent lawmaker Han Dong-hoon further fueled the debate between the ruling and opposition parties.
