HARDtalk’s Stephen Sackur speaks to Thuli Madonsela, South Africa's Public Protector until late 2016. President Zuma's grip on power in South Africa appears to be weakened.

Thuli Madonsela exposed a web of worrying connections between the state and big business interests; but are her concerns about to be brushed off?
