Winnie Madikizela-Mandela was able to tell us "what is wrong and what is right at any time". This is how ANC national chairperson Gwede Mantashe described the party stalwart and global anti-apartheid icon, who died at a Johannesburg hospital on Monday after a long illness.The African National Congress, representatives from Madikizela-Mandela's family and the Methodist Church addressed the media on Monday afternoon following her death, urging those who loved her to celebrate her life.“She is one of those who would tell us exactly what is wrong and what is right at any time. We are going to be missing that, because it’s not just being an icon based on the length of your struggle, you become an icon because of that guidance. We will be missing that guidance," said Mantashe.Mantashe’s praises for the liberation heroine were echoed by ANC secretary general Ace Magashule, who said she had dedicated her entire life to the betterment of her people and the realisation of a free South Africa.ALSO READ: South Africans take to social media to mourn Mam' Winnie"Hers was a life where she faced the harshest tribulations.
