The Blue House spokesperson has denied the rumours concerning Kim Jong-un's health and there is no evidence of his sister taking charge of the nation.
The Yonhap News Agency further added that those rumours were compounded by a report from CNN, citing an unnamed U.S. intelligence operation.
The Associated Press News article had explained that due to speculations on Kim Jong-un's health condition, it was believed that Kim Yo-jong would be in-charge of North Korea’s propaganda affairs after his death. It added that analysts said that North Korean politics and the three hereditary power transfers have been male-centred and that it would be difficult to overcome the challenges for Kim Yo-jong.
However, there is no evidence to prove that Kim's sister would become in-charge of North Korea and that Kim Jong-un is ill since the Blue House spokesperson has denied the rumours about his health.
