"We must fight to push the boundaries of patriarchy. It's a question of whether we have necessary structures to support them [victims of abuse]‚ not whether we believe them or not."
Sisulu said Khwezi was like one of Zuma's children.
"I believe there was a strong relationship between the president and Khwezi. She was part of the children in the house. She was like one of president Zuma's children."
Fezekile Ntsukela Kuzwayo‚ also known as Khwezi‚ accused Zuma of raping her at his home in Johannesburg in 2005. Zuma was deputy president of the country at the time.
Zuma denied the allegations‚ saying the sex was consensual and he was found not guilty in 2006.
Khwezi‚ who was HIV-positive‚ went into exile following the trial after receiving death threats. She returned to the country last year and passed away.
