According to the British press, “the brother of Kim Jong Un was reportedly spotted in London Wednesday, the first time he has surfaced since the North Korean leader assumed power in 2011, according to United Press International.
Kim Jong -chol, 33, was apparently in Europe to see English rock guitarist Eric Clapton in concert. Japanese television network TBS identified Kim Jong Chul in video footage from the event, according to UPI. The network said Kim, who appears to have been exiled from his country, had traveled through Beijing and Moscow to attend the concert and that the image “undoubtedly” depicted the older brother of Kim Jong-en. Kim Jong-chol’s last public appearance was in Singapore in 2011, where he had also attended a Clapton concert.”
It seems that (that’s a familial tradition), Kim Jong-chol is attending some events with representatives of the Personal Secretariat of Kim Jong-eun (including both “advisors” who are circled in orange and green in the following pictures).
The second advisor (circled in green) is also a trustee advisor on US affairs




We can also deduce that the relations between Kim Jong-eun and Kim Jong-chol are good if both of them have the same trustees advisors
