Thuli Madonsela is an inspirational example of what African public officers need to be. Her work on constitutional reform, land reform and the struggle for the protection of human rights and equality speaks for itself. As South Africa’s public protector, with her ability to speak truth to power and to address corruption in high places, Madonsela has been outstanding.

To speak about corruption in high places is often subversive and always embarrassing. The machinery of state can be called upon to intimidate or even destroy and eliminate whistle-blowers. It therefore requires extraordinary courage and patriotism to do what Thuli Madonsela has done. Yet in standing up for the truth as she sees it, she has assured herself a place in the history of modern South Africa and among the tiny but growing band of African public servants giving us hope for the future of our continent.

Sanusi was governor of the Central Bank of Nigeria from 2009 to 2014
