SEOUL (Reuters) – South Korea’s leadership crisis deepened on Sunday as prosecutors named President Yoon Suk Yeol as a subject of a criminal investigation over last week’s martial law attempt, a media report said, and his former defence minister was arrested.
Yoon survived an impeachment vote in the opposition-led parliament late on Saturday, prompted by his short-lived attempt to impose martial law on Tuesday, but the leader of his own party said the president would effectively be excluded from his duties before eventually stepping down.
That proposal, which appeared to win tacit approval from the Yoon-appointed prime minister on Sunday, drew condemnation from opposition lawmakers who said it was another unconstitutional power grab to delegate authority without resignation or impeachment.
Thousands of people rallied in front of the parliament in Seoul on Sunday, calling for the impeachment and arrest of Yoon and the disbandment of his ruling party.
Yoon’s martial law declaration on Tuesday plunged Asia’s fourth-largest economy and a key U.S. military ally into its greatest political crisis in decades, threatening to shatter South Korea’s reputation as a democratic success story.
The leader of Yoon’s People Power Party, Han Dong-hoon, told a press conference alongside the prime minister on Sunday that Yoon would not be involved in foreign and other state affairs before his early resignation.
But National Assembly speaker Woo Won-shik said it was unconstitutional to delegate presidential authority to the prime minister and the ruling party without impeachment. Woo proposed a meeting of rival parties to discuss ways to suspend Yoon’s presidential power immediately.
The main opposition Democratic Party called for the immediate suspension of Yoon’s presidential duties and for stripping him of authority to control the military. The DP called for the arrest of Yoon and related military officials implicated in the martial law fiasco.
Yoon shocked the nation on Tuesday night when he gave the military sweeping emergency powers to root out what he called “anti-state forces” and obstructionist political opponents. He rescinded the order six hours later, after parliament defied military and police cordons to vote unanimously against the decree.
Yonhap news agency reported that prosecutors had “booked” Yoon, a process in South Korea that involves formally naming subjects of investigation.
Prosecutors could not immediately be reached for comment on the report.
Three minority opposition parties filed a complaint with the prosecution against Yoon, ex-Defence Minister Kim Yong-hyun and martial law commander Park An-su, accusing them of insurrection. The crime of leading an insurrection is punishable by death or life imprisonment, with or without prison labour.
Kim, who stepped down on Wednesday after Yoon rescinded martial law, was seen as a central figure in the debacle. He had proposed martial law to the president, according to a senior military official and the impeachment filings.
The prosecution’s special investigative team arrested Kim on Sunday and seized his mobile phone, it said in a brief statement to reporters. Before the arrest, investigators questioned Kim, who voluntarily appeared at the Seoul Central District Prosecutors’ Office around 1:30 a.m. on Sunday (1630 GMT on Saturday), Yonhap news agency reported.
The national police raided Kim’s office on Sunday as part of an investigation into claims of treason against Yoon and top ministers, Yonhap said.
Opposition lawmakers allege Yoon mobilised military forces to block a vote by lawmakers seeking to nullify what they said was an unconstitutional martial law decree.
