PUBLIC Enterprises Minister Stella Sigcau has called for a review of the tender process at ports and harbours parastatal Portnet, following claims of unfair procedures and corruption at its black empowerment office. Following discussions last week with Transnet MD Saki Macozoma, Sigcau said it has been decided to examine tender procedures at Portnet. A ministry spokesperson said on Monday the decision relates to allegations of nepotism at Portnet’s Durban black empowerment office.
