Marxist-Leninistiska Kampförbundet (Swedish: [markˈsɪ̂sːtlɛnɪˌnɪstɪska ˈkâmpfœrˌbɵndɛt] ⓘ; MLK; English: Marxist-Leninist Struggle League), full name Marxist-leninistiska kampförbundet för Sveriges kommunistiska parti (m-l; English: "Marxist-Leninist Struggle League for the Communist Party of Sweden"), was a communist political organization in Sweden formed in 1970 by Vänsterns Ungdomsförbund (Left Youth League), the youth organization of VPK.
Notable former members include later Left Party leader Gudrun Schyman.
Between 1980 and 1982, MLK and Kommunistisk Ungdom, the new VPK youth organisation, were involved in a legal dispute over the right to publish newspapers using the name Stormklockan, with MLK winning the dispute in the Court of Appeal for Western Sweden.
[2] MLK maintained four bookstores, named after Set Persson, in Stockholm, Trollhättan, Sundsvall and Kiruna.
In 1981, MLK unified itself with Röd Ungdom, the youth organization of SKP.
