North Korea revealed Thursday the official title of Kim Jong-Un’s younger sister, who is widely tipped to become a close and influential aide to the young leader. Kim Yo-Jong, believed to be 26, made her first public appearance during the funeral of her father and longtime ruler Kim Jong-Il in December 2011. Since then, she has occasionally been seen accompanying her brother to political events and on his “field guidance trips,” but without any specific title attached to her name. That changed Thursday when the North’s official KCNA news agency listed her as a “vice department director” in the central committee of the ruling Workers’ Party. North Korean watchers have speculated that Kim Yo-Jong may end up playing the same leadership supporting role as her powerful aunt, Kim Kyong-Hui.
