North Korea said on Wednesday it 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.
