Yoon's brief declaration of martial law threw South Korea into political chaos and put his own political fate in jeopardy as opposition lawmakers openly called for his removal from office.

Axar.az reports that citing Yonap Agency, the main opposition Democratic Party (DP) said it will file treason charges against Yoon as well as his defense and interior ministers and impeach them to hold them accountable for the action.

DP leader Lee Jae-myung called the martial law declaration "illegal," asserting Yoon is "no longer the president" of South Korea.

The parliament must vote on whether to proceed with impeachment within 72 hours after the motion is reported to the plenary session, which would require a two-thirds majority in the 300-member parliament to pass.

The DP and other small opposition parties together have 192 seats, which means at least eight out of 108 PPP lawmakers need to support the impeachment for it to pass.

If successful, the Constitutional Court would then rule on whether Yoon's removal from office is warranted.

During the court's deliberation, the president's constitutional powers would be suspended, and Prime Minister Han Duck-soo, as the No. 2 official in the government, would assume presidential responsibilities.
