ChainCatcher News, according to Yonhap News Agency, after South Korean President Yoon Suk-yeol announced the implementation of a state of emergency and lifted it more than six hours later, South Korea's largest opposition party, the Democratic Party, urged Yoon to resign immediately and stated that if he does not resign, they will advance impeachment proceedings.

The Democratic Party issued a resolution containing the above content after convening an emergency meeting of lawmakers in the National Assembly. The resolution stated: "Yoon Suk-yeol's announcement of a state of emergency clearly violates the Constitution, and he did not comply with any conditions required for declaring the state of emergency; the declaration of a state of emergency itself is invalid and constitutes a serious constitutional violation, which is a severe act of internal unrest and 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 promptly initiate impeachment proceedings."
