The group broke away in 1977, and formed Arbetarpartiet Kommunisterna ('Workers Party – the Communists', abbreviated APK).

A large number of foreign delegates attended the congress, indicating that APK had strong moral support from CPSU and the orthodox sector of the World Communist Movement.

Two MPs (and party central committee members), Rolf Hagel and Alf Löwenborg, led the split.

Entire VPK party units joined APK in many places, including Malmö, Gothenburg and Mälardalen.

In 1995, APK was declared financially bankrupt by state authorities, the first political party in Sweden to suffer that fate.
