North Korea's new young leader will have to share power with an uncle and the military after the death of his father Kim Jong-il as the isolated country shifts to collective rule from strongman dictatorship.
The military, which is trying to develop a nuclear arsenal, has pledged allegiance to the untested Kim Jong-un who takes over the family dynasty that has ruled North Korea since it was founded after world War Two.
Jang Song-thaek, 65, brother-in-law of Kim Jong-il and the younger Kim's uncle, was named in 2009 to the National Defense Commission, the supreme leadership council Kim Jong-il led as head of the military state.
