South Korea's impeached President Yoon Suk Yeol has been charged with insurrection after he attempted to declare martial law in December, BBC reported.
His ill-fated attempt to impose military rule plunged the country into an unprecedented political crisis and he becomes the first sitting president in South Korean history to be charged with a crime.
The indictment comes after a court in Seoul rejected a request to extend Yoon's detention on Saturday, which meant prosecutors had to make a decision on whether to charge or release him before Monday.
"The punishment of the ringleader of insurrection now begins finally," Han Min-soo, a spokesman from the main opposition Democratic Party told a press conference.
Separately, the Constitutional Court has begun deliberations on whether to formally dismiss Yoon as president or reinstate him.
The impeached president has largely refused to co-operate with the criminal investigation over the martial law declaration.
Yoon is set to stand trial along with his former defence minister and senior military commanders, who are accused of helping him plan and carry out the attempt to seize total power.
In an unprecedented televised announcement on December 3, Yoon said he was invoking martial law to protect the country from "anti-state" forces that sympathised with North Korea.
At the time, the embattled leader was in a deadlock over a budget bill, dogged by corruption scandals and several of his cabinet ministers were under investigation.
The military announced all parliamentary activity was suspended and sought to impose controls on media outlets.
The opposition's Democratic Party leader Lee Jae-myung urged people to protest at the National Assembly and asked his fellow lawmakers to immediately vote to repeal the order.
