Kim Nam-jun, the spokesperson for the Blue House, submitted his resignation on the 20th, stating his intention to run in the byelection for Incheon Gyeyang, which was previously represented by President Lee Jae-myung. At a press conference, Kim confirmed that today would be his final day of work and that the processing of his resignation would occur on Monday. His career has closely followed that of President Lee, starting from his role in regional broadcasting to various significant positions during Lee's tenure as mayor, governor, and presidential candidate.

The political landscape in Gyeyang is becoming increasingly competitive, especially following the recent developments involving Song Young-gil, the former chairman of the Democratic Party, who was acquitted in the 'party conference money envelope' scandal. Song is reportedly preparing to run for the byelection in Gyeyang after officially requesting to rejoin the Democratic Party, which raises tensions within the party as they may have to navigate the candidacy of two prominent figures for the same position. Song is expected to have already registered his residency in the district, positioning himself as a formidable candidate ahead of the election.

In addition to these developments, Park Chan-dae, a sitting Democratic Party member, is a confirmed candidate for the Incheon mayoral election, which may lead to additional reshuffling of candidates in other local races, particularly in his district of Incheon Yeonsu-gap. This implies that the Democratic Party may be faced with strategic decisions to ensure that they maintain a competitive edge across various electoral contests amidst the upcoming byelections.
