Impeached South Korean leader Yoon Suk Yeol is due to attend the first hearing of his criminal trial to face charges that he led an insurrection when he declared martial law late last year and plunged the country into months of turmoil.

Mr Yoon’s declaration that martial law was needed in part to root out “anti-state” elements was lifted six hours later after parliamentary staffers used barricades and fire extinguishers toward off special operations soldiers trying to enter parliament, where politicians voted to reject martial law.

Mr Yoon, who has denied all charges against him, is due to attend the trial at the Seoul Central District Court this morning at 10am (2am Irish time) as required by law for a defendant in a criminal trial.


Hundreds of supporters shed tears as they watched Yoon Suk-yeol leave the official residence

The charge of insurrection faced by the impeached leader is punishable by life imprisonment or even death, although South Korea has not executed anyone in decades.

Mr Yoon was removed by the Constitutional Court from office earlier this month for violating constitutional powers with actions that were labelled “a serious challenge to democracy”.

His martial law declaration on 3 December shocked South Koreans, and created chaos in all areas of society, the economy and foreign policy, the Constitutional Court said.

The upheaval has further exposed deep social rifts between conservatives and liberals and stepped up pressure on institutions and the military, which had found itself in a quandary over whether to enforce martial law.


The country will hold a snap election on 3 June

The former president returned to his private home on Friday from the official residence, with crowds of conservative supporters turning out to greet his motorcade.

He remains defiant and has pledged to “stand by” his supporters.

The country will now hold a snap election on 3 June. Questions remain over whether Mr Yoon might still play a role.

For the criminal hearing today, two senior military officers are expected to take the witness stand.

One of them, Cho Sung-hyun from the army’s capital defence command, already testified at the Constitutional Court in February that he was ordered to send troops to “drag” politicians out of parliament during Mr Yoon’s martial order rollout.
