I will explain the Workers Party of Korea, the ruling party of North Korea.
Article 11 of the North Korean Constitution (Democratic People’s Republic of Korea Socialist Constitution) states, “The DPRK will undertake all activities under the leadership of the DPRK.”
In this regard, the following sentence summarizes everything.
As the saying goes, “All power comes from the party.” In the north, the party is in control of the State Council, the army, speech, and social groups. (Kang Myeong-do, “North Korea’s Top Secret,”）
The State Council is the Cabinet. The Workers Party of Korea has ruled not only the government but also the corporations.
North Korean enterprises (company) have a dual structure of a “management organization” that manages business and a “party organization” that supervises it. The top of the management organization is the manager, the top of the party organization is the party secretary, but the actual top is the party secretary. (Kim ki-sung, “Introduction to Life in North Korea”
The Workers Party of Korea has a hierarchy from the center to the end.
The terminal organization of the Workers Party of Korea is the party cell. It is composed of five to twenty people, led by the cell secretary, and the members of the cell party gather to form an introductory party committee. There is a divisional party between the elementary party and the party cell, and if the number of party members exceeds thirty, an elementary party can be formed. The elementary party leader is the elementary party secretary, who organizes around a hundred members. Elementary parties gather to form party committees for cities and counties, and large business establishments are designated as factory party committees. Then, the party committee of the city and county and the factory party committee come together to form a provincial party, and the party central committee of the central party, which is the top, controls each provincial party. Party members follow the party organization, lower party organizations follow the senior party organization, and all party organizations absolutely submit to the Party Central Committee. (Ibid.)
The party also manages local governments, and the head of each local government is a party executive.
The chief of Onsong is the city secretary. Next is the head of the Municipal Administration Committee, with propaganda representatives and distribution executives below. (Kang Hyuk, Children of North Korea)
