PANews, December 4 - According to the latest report from Yonhap News Agency, after South Korean President Yoon Suk-yeol announced the implementation of martial law and lifted it more than six hours later, the largest opposition party, the Democratic Party, urged Yoon Suk-yeol to resign immediately and stated that if he does not resign at once, they will advance impeachment proceedings. It was reported that the Democratic Party issued a resolution containing the above content after convening an emergency parliamentary meeting that day. The resolution stated: 'Yoon Suk-yeol's announcement of the implementation of emergency martial law is a clear violation of the constitution and did not meet any of the necessary conditions required for announcing (martial law). The announcement of emergency martial law itself is invalid and is a serious unconstitutional act. This is a serious act of internal turmoil and is a perfect reason for impeachment.' The Democratic Party stated, 'If Yoon Suk-yeol does not resign immediately, we will represent the will of the people and immediately enter the impeachment process.'
