Lee Jong-myeong served as third deputy director of South Korea’s National Intelligence Service (NIS) under the conservative administration of Lee Myung-bak. In 2013, Lee was succeeded by another conservative president, Park Geun-hye, who is currently serving a 25-year prison sentence for corruption. As intelNews has previously reported, several senior NIS officials, including three of its former directors, have been sentenced to prison for diverting agency funds to psychological operations aimed at preventing the election of liberal politicians.

Now the probe into the NIS’ illegal political activity has expanded to include the organization’s mid-level management, including Lee Jong-myeong. On Monday, the Seoul Central District Court found Lee guilty of spending nearly $500,000 from the NIS’ clandestine operations budget to discredit two liberal former presidents, Roh Moo-hyun and Kim Dae-jung. The goal of the campaign was to convince the South Korean electorate that a future liberal president would surrender the reigns of the country to North Korea.

These revelations have sparked a major overhaul of South Korea’s intelligence system, which some observers have described as the NIS’ “most dramatic shake-up in decades”. The government reportedly intends to prevent the NIS from having any domestic role, and to limit its operations to foreign targets. But some conservative politicians have accused the current administration of left-of-center president Moon Jae-in of “defanging” the NIS.
