Choe Ryong-hae
According to the North Korean constitution, Kim Jong-un is part of a triumvirate heading the executive branch of the North Korean government along with Premier Kim Tok-hun and parliament president Choe Ryong-hae. Kim Jong-un commands the armed forces, Kim Tok-hun heads the government and handles domestic affairs, and Choe Ryong-hae handles foreign relations. However, under the constitution, Kim Jong-un is the highest-ranking of the three. Since 1998, the NDC chairmanship has been constitutionally defined as "the highest post in the state", and a constitutional amendment enacted by Kim Jong-un explicitly named the NDC (first) chairman as "the supreme leader of the Democratic People's Republic of North Korea". However, analysts are divided about how much actual power Kim has.
