COMMUNICATIONS Minister Ivy Matsepe-Casaburri said on Monday she will block the awarding of a third cellular licence if evidence of bid tampering comes to light. But Matsepe-Casaburri added that despite two probes over allegations of corruption in the South African Telecommunications Regulatory Authority (Satra), the evaluation of bids for the lucrative licence is on schedule. Satra, the country’s telecommunications industry watchdog, is due to present the minister with its final decision on the licence winner on or around December 24. But Satra itself is currently under investigation by the office of the auditor-general after parliament’s communications portfolio committee slammed the body for incompetence and defective decision-making last month.
