In an exclusive interview with ITV News, Winnie Mandela said she would make the same sacrifices and "do it all over again" to ensure the liberation of South Africa.
Speaking to ITV News presenter Mark Austin, Ms Mandela said: "I would do that 100 times more. I need to go back to those days.
"We had to fight that bitter struggle. I would do it all over again. There is no greater reward than the one we both had of a liberated South Africa".
ITV News presenter Mark Austin reports from Soweto in South Africa:
She said her fondest memory of ex-husband Nelson Mandela was "the little time we spent together":
Following the former South African president's death, Ms Mandela said she was now "head of the family", adding, "It is not a case of assuming anything ... It is the traditional right".
Asked whether she would now inherit the Mandela mantle politically speaking she laughed, saying: "We never even planned to be who we are in this struggle.
"It’s not for me to say, ‘Yes, here I am inheriting a political position’. No we’ve never done that.”
