The Korean Social Democratic Party (KSDP) is a political party in North Korea that is allied with the ruling Workers' Party of Korea (WPK). It was formed on 3 November 1945 as the Korean Democratic Party by a mixed group of entrepreneurs, merchants, handicraftsmen, petite bourgeoisie, peasants, and Christians. The party's founders were motivated by anti-imperialist and anti-feudal aspirations, and aimed to eliminate the legacy of Japanese rule and build a new democratic society. The party came under greater influence of the ruling government over time, and today is under the effective control of the WPK.

The Supreme People's Assembly is the legislature of North Korea. It is ostensibly the highest organ of state power and the only branch of government in North Korea, with all state organs subservient to it under the principle of unified power. However, in practice it is a rubber stamp legislature which exists to approve decisions made by the ruling party as a formality, and which has little to no real power of its own.
