NORTH Korea has issued a standing order for the execution of former South Korean President Park Geun-hye and her spy chief for a plot to assassinate its leader.

The North’s official KCNA said “revelation showed” Park had masterminded a plot to execute its “supreme leadership” in 2015 and it was imposing the “death penalty on traitor Park Geun-hye”.

KCNA did not disclose the source of the revelation but a Japanese newspaper reported this week that Park in 2015 approved a plan to overturn the North Korean regime of leader Kim Jong-un.

Park was ousted in March over a corruption scandal and is in detention while on trial.

South Korea’s National Intelligence Agency (NIS) said the news report of a plot to kill Kim “had no grounds” and it had no immediate comment about the North’s demand for the handover of Park and her spy chief, Lee Byung-ho. Lee is no longer head of the NIS.

“We declare at home and abroad that we will impose the death penalty on traitor Park Geun-hye and ex-director of the puppet intelligence service ... criminals of hideous state-sponsored terrorism who hatched and pressed for the heinous plot to hurt the supreme leadership of the DPRK,” KCNA said.

DPRK stands for the Democratic People’s Republic of Korea, the North’s official name.

“We declare that in case the US and the South Korean puppet forces again attempt at hideous state-sponsored terrorism targeting the supreme leadership ... we will impose summary punishment without advance notice,” KCNA said.

KCNA said the statement was issued jointly by the North’s Ministry of State Security, the Ministry of People’s Security and the Central Public Prosecutors Office.
