Marxist-Leninistiska Kampförbundet, 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 (m-l)), was formed in 1970 by Vänsterns Ungdomsförbund (Left Youth League), the youth organization of VPK. Within VUF several ultraleftist tendencies had surged during the 1960s, orientating it toward Maoism. VUF broke with VPK in 1968, and in 1970 they formed MLK. MLK was ideologically almost identical with the larger KFML/SKP, with Marxism–Leninism-Mao Tse-Tung Thought as the ideological backbone. MLK supported KFML/SKP in elections.
