North Korean media said on Wednesday that the soon-to-retire UN Secretary General Ban Ki-moon is not worthy presidential material, amid South Korean poll results showing him to be a favorite to win the 2017 election.

The North Korean state-run outlet Uriminzokkiri referred to Ban as the “first-class extreme conservative cell Ban Ki-moon” in a video uploaded on Wednesday.

Referring to the South Korean poll results, Uriminzokkiri slammed Ban as an “experienced American spy,” who would only extend the anti-North policies of the past by following U.S. orders during his presidency.
