North Korea’s ailing leader has chosen his youngest son — who is just 26, attended a Swiss boarding school and reportedly admires basketball great Michael Jordan — as heir to the family dynasty that rules the secretive state, South Korea’s intelligence service told lawmakers in Seoul.

Kim Jong-un is the third son of Kim Jong Il, the “Dear Leader” who suffered a stroke last summer and who has since appeared thin and frail. He is the grandson of the late Kim Il Sung, the “Great Leader” and founding dictator of North Korea.
