Former Democratic Alliance parliamentary leader Lindiwe Mazibuko officially graduated from Harvard U.
Sandile Patrick Zweni said he should be granted bail because he needed to look after his children. Magistrate Anita Govender rejected his application.
Zweni and his co-accused - Nonduzo Dlamini, Bhabha Dubazini, Dr Genchen Ragnath and his wife Ravina - face charges of dealing in cocaine, human trafficking, running a brothel and living off the earnings of prostitution.
The case was remanded to May 24.
