Suspended President Yoon Suk Yeol said on Tuesday South Korea had been facing an "existential crisis" when he declared martial law last year, remaining defiant and unapologetic as he faced the final day of impeachment hearings that could formally remove him from office.

SEOUL, Feb. 25 (Yonhap) -- The Constitutional Court will hold the final hearing of President Yoon Suk Yeol's impeachment trial Tuesday, which will present the final arguments of the legal teams of both Yoon and the National Assembly, serving as the prosecution in the case.

South Korean President Yoon Suk Yeol is expected to make a closing statement on Tuesday in a Constitutional Court trial reviewing his impeachment, as public hearings wrap up and his political fate is placed in the hands of eight judges.
