As per many officials of Seoul, Kim Jong Un is busy delegating his responsibilities and his sister Kim Yo Jong who is running one of the most important political bodies in North Korea, officials in Seoul believe, has become his second-in-command. If it is indeed true, then it makes her the second-most powerful person in South Korea.  

For quite some time now, there have been many conflicting news reports fueling speculations that Kim Jong Un's is not well and that is the reason that he is shifting his responsibilities. This makes the North Korean leader's younger sister Kim Yo Jong, a senior government official, his possible successor.

She "is, as best we can tell, a very capable and high-skilled member of the North Korean leadership — and is not one to underestimated by any stretch of the imagination,” Harry J. Kazianis, the senior director of Korean Studies at the Center for the National Interest, told TIME.

At the National Assembly on August 25, South Korea's defence minister, Jeong Kyeong-doo addressed the lawmakers by commenting on Kim Yo Jong’s powerful status. He also claimed that she is most probably in charge of the Organization and Guidance Department (OGD) of North Korea's ruling Workers' Party (WPK), that is responsible for ideological indoctrination, party organization and political appointments.

According to experts, the OGD also monitors the estimated 3 million members of the WPK, ensuring that they are loyal to Kim Jong Un and adhere to the North Korean regime. A trusted confidante and supporter of her brother for years, Kim Yo Jong has previously served as one of North Korea's top propagandists. Currently, she was named an alternate Politburo member of the country's Workers' Party of Korea. 

And now, as per Jeong, along with her speculated responsibilities mentioned above, Kim also has an important role in shaping policy toward South Korea as well as the United States of America. Recently, South Korea's National Intelligence Service (NIS) had made the assessment that Kim Jong Un had decided to distribute more of his powers and responsibilities to his senior officials, which includes his sister Kim Yo Jong so as to lessen- his towering workload.
