Ellis also found evidence that Mandela had been an active member of the South African Communist Party during the late 1950s and early 1960s, something that was confirmed after his death by both the ANC and the SACP, the latter of which claimed that he was not only a member of the party, but also served on its Central Committee.
Ellis tamén atopou probas de que Mandela fora membro activo do Partido Comunista de Suráfrica durante os últimos anos 1950 e comezos dos anos 1960, feito confirmado trala súa morte tanto polo CNA como polo propio Partido Comunista, este último afirmando que non só fora membro do partido, senón que servira tamén no seu comité central.
