(London Telegraph) For decades, it was one of the enduring disputes of South Africa's anti-apartheid struggle. Was Nelson Mandela, the leader of the African National Congress, really a secret Communist, as the white-only government of the time alleged? Or, as he claimed during the infamous 1963 trial that saw him jailed for life, was it simply a smear to discredit him in a world riven by Cold War tensions?
Now, nearly half a century after the court case that made him the world's best-known prisoner of conscience, a new book claims that whatever the wider injustice perpetrated, the apartheid-era prosecutors were indeed right on one question: Mr Mandela was a Communist party member after all.
The former South African president, who won the Nobel Peace Prize in 1993, has always denied being a member of the South African branch of the movement, which mounted an armed campaign of guerrilla resistance along with the ANC.
