"And yet we speak about it in a cynical way.#TutuPeaceLecture As directed by programme director Claire Mawisa, it’s time to sing Happy Birthday ‘to our beloved Arch’ @TeamNews24 pic.twitter.com/pwf7iLvV0t— Kamva Somdyala (@kamva_somdyala) October 7, 2019#TutuPeaceLecture ‘The problem with corruption is that the people who are engaging in it, don’t think anyone else knows about it,’ says Masiyiwa. @TeamNews24 pic.twitter.com/Q31gDI2Wbe— Kamva Somdyala (@kamva_somdyala) October 7, 2019"To defeat it, we need better legislation to deal with it. We need stronger accountability measures."Masiyiwa said revelations of alleged corruption currently being heard at the Zondo commission of inquiry into state capture should lead to prosecutions. "Corruption is not inevitable and unstoppable. "That's what the corrupt want you to believe. To move back to the founding values of our liberation as a continent, we must fight corruption," added Masiyiwa."And make no mistake, both giver and receiver are corrupt."Corruption has no colour," he emphasised. ‘Corrupt people want you to believe that corruption is both unstoppable and inevitable. We need to change that mindset,’ says Masiyiwa at #TutuPeaceLecture @TeamNews24— Kamva Somdyala (@kamva_somdyala) October 7, 2019Earlier, the board CEO of the Desmond and Leah Tutu Legacy Foundation, Niclas Kjellström-Matseke, paid tribute to Tutu, who was in attendance with his family, saying "while you have retired from public life, the struggles you fought for have not retired".
