The wife of South Korea’s jailed ex-President Yoon Suk Yeol and his former prime minister were indicted Friday as part of investigations into his administration and his attempt to overcome opposition by declaring martial law.

Yoon set off South Korea’s most serious political crisis in decades when he attempted to overcome an opposition-dominated legislature that blocked his agenda by abruptly declaring martial law. His decree lasted only hours but triggered months of turmoil that paralyzed politics, disrupted foreign policy and rattled the economy.

Yoon was impeached, then removed from office in April and rearrested last month after his conservative party lost a special election to choose his successor. The new government has appointed three special prosecutors to investigate both the period of martial law and suspicions of corruption that dogged Yoon through his term in office.

Yoon’s wife, ex-prime minister becomes the latest figures to be indicted

A team led by Special Prosecutor Min Joong-ki said it charged Yoon’s wife, Kim Keon Hee, with violating financial market and political funding laws and receiving bribes, about two weeks after she was arrested.

A separate team led by Special Prosecutor Cho Eun-suk said former Prime Minister Han Duck-soo was charged with abetting Yoon’s imposition of martial law, which investigators say amounted to a rebellion, as well as falsifying and destroying official documents, and lying under oath.

Dozens of people have been arrested or investigated over Yoon’s martial law debacle, corruption allegations involving his wife, and other controversies from his three years in office, including an alleged cover-up of a marine’s drowning death during a 2023 flood rescue operation.

Assistant special prosecutor Park Ji-young told a televised briefing that Han was the highest official who could have blocked Yoon’s attempt to impose martial law. Park said Han still played an “active” role in Yoon’s martial law declaration by trying to get Yoon’s decree passed through a Cabinet Council meeting as a way to give “procedural legitimacy” to it.

Han has maintained he conveyed to Yoon that he opposed his martial law plan.

Cho’s team earlier requested the Seoul Central District Court to issue a warrant to arrest Han. But the court on Wednesday dismissed that request, saying it determined that there were little chances that Han would flee or destroy evidence.

While Yoon’s self-inflicted downfall extended a long streak of South Korean presidencies ending badly, Kim is the first former first lady to be arrested and indicted.

Nearly every former South Korean president, or their family members and aides, have been mired in scandals near the end of their terms or after they left office.

The last two presidents elected from earlier iterations of Yoon’s party – Park Geun-hye and Lee Myung-back — were both sentenced to lengthy prison terms over corruption charges before being pardoned and released.

Yoon’s surprising but poorly-planned martial law imposition came amid an intense standoff with the liberals, but many critics have speculated Yoon’s move was mainly likely an attempt to frustrate then an opposition-led push to open an independent investigation into his wife’s allegations.

Kim and Yoon are suspected of exerting undue influence on the conservative People Power Party to nominate a favored candidate in a 2022 legislative by-election, allegedly at the request of election broker Myung Tae-kyun. Myung is accused of conducting free opinion surveys for Yoon that used manipulated data, possibly helping him win the party’s presidential primaries before his election as president in March 2022.

In a statement released through her lawyers on Friday, Kim didn’t make specific comments about her charges, but said the media was reporting suspicions as though they were “confirmed fact” and that she plans to “quietly attend the trials.”

Han, who was appointed prime minister, the country’s No. 2 post, by Yoon, was South Korea’s acting leader after Yoon was impeached in mid-December.

After Yoon was formally dismissed as president in a Constitutional Court decision, Han was supposed to continue to head the caretaker government until the June presidential election, but resigned to run for the election. He withdrew from the race after failing to win the People Power Party’s nomination.
