In light of the fact that the Development Bank of South Africa (DBSA) has been at the helm as the implementing agency for the Telkom Towers project since 2015, and to date the project has not been completed despite numerous promises to do so, what are the reasons that the DBSA is still retained as an implementing agency despite the fact that the Portfolio Committee on Public Works and Infrastructure does not have jurisdiction over DBSA but the Independent Development Trust which is an entity within her department and has a responsibility to provide infrastructure according to its mandate?
