She also questioned why men in the struggle weren't subjected to the same scrutiny, and said, "double standards obscure the enormous efforts of women" in the struggle.
Earlier, Malema's speech opened up all wounds when he directly addressed the fallen hero and said, "Mama, there are sell-outs here".
He also attacked ANC leaders who called her a criminal and who further prevented her from speaking at youth struggle icon Peter Mokaba's funeral.
In his address, he spoke directly to Madikizela-Mandela whom he had a close relationship with.
The Mother of the Nation was finally in her resting place sandwiched between her great grandchildren, Zenawe and Zenani Mandela. "We know her. We don't need (former police commissioner during Apartheid) George Fivaz to tell us about Winnie Mandela‚" Malema said, in apparent reference to a TV documentary broadcast this week which revealed that the police did everything in their power to tarnish her image, including allegations that she killed a young footballer named Stompie. She took on the most evil and powerful regime of the past century.
He said he had a conversation with her shortly before her death about her worries and her wishes.
Earlier that day at Orlando Stadium, Malema gave a fiery speech in tribute to the lat struggle icon.
Winnie Mandela, former wife of Nelson Mandela, died recently at the age of 81 in South Africa and was laid to rest at a massively attended funeral last weekend in her hometown of Soweto.
Police are reportedly investigating an alleged scuffle between Police VIP protection unit and EFF members Julius Malema and fellow Member of Parliament Mbuyiseni Ndlozi.
Malema received the loudest cheers at the Orlando Stadium in Soweto on Saturday.
Munusamy added that one could see a very deliberate effort by President Cyril Ramaphosa to reach out to the EFF leader Julius Malema during Saturday's funeral for Mam'Winnie.
Malema also said that Ramaphosa was Madikizela-Mandela's President and not Zuma, who had ignored her.
