The main opposition Democratic Party of Korea (DPK) will introduce a motion for the dismissal of Foreign Minister Park Jin unless he is sacked immediately for mishandling President Yoon Suk-yeol's latest overseas trip marred by Yoon's use of foul language, the party's floor leader said Monday.

"If President Yoon does not make a decision by today, we will introduce a motion tomorrow recommending the dismissal of the foreign minister in order to restore people's trust and remedy foreign policy," Rep. Park Hong-geun said during a meeting of the party's Supreme Council.

Park also called for the replacement of National Security Adviser Kim Sung-han, the first deputy director of the National Security Office Kim Tae-hyo and senior press secretary Kim Eun-hye.

The DPK has denounced Yoon's three-nation trip as a "diplomatic disaster."
