Kim Jong-Il's third son, the likely successor to the North Korean leader, has been appointed acting defense chief under his ailing father, a Japanese newspaper reported on Saturday.
Kim Jong-Un started supporting his father as acting chairman of North Korea's National Defense Commission, the evening edition of the Mainichi Shimbun said, quoting unnamed sources close to North Korean leadership.
Kim Jong-Il has held its two highest posts of defense commission chairman and secretary general of the Workers' Party of Korea, since his father, Kim Il-Sung, died in 1994.
While the role of acting chairman is still considered informal, the 26-year-old son appears to be securing his succession to his father."Mr. Kim Jong-Un is now concentrating on the job of deputy chairman," the source said. "If something happens to our general, the chairman's position will be automatically taken by (Jong-Un)."
