The SACP's Solly Mapaila says he has apologised to the family of former PAC leader Robert Sobukwe as well as the party's current leadership for comments he made.
On Wednesday, IOL reported that Mapaila described Sobukwe as someone who was favoured by the apartheid regime.
Mapaila reportedly made the comments on Tuesday at a dialogue celebrating the Rivonia Triallists at Liliesleaf Farm in Rivonia.
But, in a statement released on Thursday, Mapaila said he offered "an unreserved apology" to the Pan Africanist Congress of Azania (PAC), the Sobukwe family as well as Sobukwe's legacy.
"This morning I met the leadership of the PAC, President Narius Moloto, to express my apology. I have also spoken with the Sobukwe family, through Dini Sobukwe, to express my profound apology and will create time to visit the family in person. I will also engage other leaders of the PAC on the matter."
He added that while his apology was unreserved, he wanted to clear up some "distortions" that had been made by "some elements in the media".
