2013 South Korean sabotage plot

In August 2013, South Korea's spy agency, the National Intelligence Service, accused Lee Seok-ki, a lawmaker from the leftist Unified Progressive Party (UPP), of plotting to overthrow the country's democratically elected government if war broke out with North Korea. He allegedly led a secret May meeting of 130 members of his party aimed at attacking South Korean infrastructure if the heightened tensions between Koreas in the spring of 2013 had led to war.

After further investigation, on September 26, 2013, South Korean prosecutors indicted Lee Seok-ki on charges that he was plotting a pro-North Korea rebellion to overthrow the government, saying his plan posed a "grave" national security threat.

On 17 February 2014, he was sentenced to 12 years of prison by a district court.

"The National Intelligence Service carried out detailed investigations into this case for the past three years and confirmed Representative Lee Seok-ki is suspected of assisting the national enemy and conspiring in a rebellion based on various evidences, such as the testimony of witnesses, the comments Lee made at several secret meetings, confiscated documents and some other materials contained in USB devices," Justice Minister Hwang Kyo-an said during a speech at the National Assembly on September 4, 2013.

The 10 major suspects who had been investigated by NIS are Lee Seok-ki (a lawmaker of the UPP), Woo Wi-young (an ex-spokesman of the UPP), Kim Hong-ryul (the Kyunggi provincial chairman of the UPP), Kim Keun-rae(a Kyunggi provincial vice chairman of the UPP), Hong Soon-seok(a Kyunggi provincial vice chairman of the UPP), Lee Sang-ho(an adviser of Kyunggi Alliance for Progressive Movement), Lee Young-chun(a Kyunggi-Paju branch manager of Korean Confederation of Trade Union), Jo Yang-won(the representative of Social Trend Institute), Han Dong-geun(a former Suwon city chairman of the UPP), Park Min-jung(a former youth chairman of the UPP). NIS had acquired court approvals for wiretapping and had been collecting a wide range of evidence by closely monitoring the secret meetings of Lee Seok-ki and his colleagues. The NIS is said to have secured recordings of Lee's speech at a meeting of the East Kyunggi Coalition, the mainstream faction of the UPP
