Mandela Park Backyarders say they have 'proof of corruption' in a Khayelitsha housing project and have called for the 'immediate' resignation of Western Cape Human Settlements MEC Bonginkosi Madikizela. The call follows the organisation’s online publication of results of their investigation into the occupation of houses in the Mandela Park Housing Project, of which 150 houses out of a planned 950 have been completed.
