South Korean President Yoon Suk Yeol is due to attend on Tuesday a Constitutional Court hearing of his impeachment trial where the detained leader may get a chance to argue his case or answer questions over his short-lived bid to impose martial law.

The impeached president is using unsubstantiated claims of election interference by China and North Korea to justify his failed self-coup bid.

A Seoul court issued a warrant Saturday to detain impeached President Yoon Suk Yeol for an extended period over his botched martial law bid last month in the first such detention of a sitting South Korean president.
