PRETORIA - Investigating Directorate Against Corruption (Idac) head Advocate Andrea Johnson is appearing before the Madlanga Commission on Tuesday.
This after she missed last week Monday's scheduled testimony due to illness.
Her testimony comes after the Commission heard explosive claims from senior IDAC officials. They have painted a picture of an organisation plagued by internal divisions and punitive culture.

Johnson also faces mounting allegations over links to senior Crime Intelligence officer Feroz Khan and claims that she leaked details of a criminal complaint to him.
She denies this but the NPA has since expressed concern over the impact of the allegations on IDAC's credibility and public trust.
