"Our starting point was that we want a 100% audit because if it happened in the 200 or so cases we know about it, it could have happened in 20,000 cases. We are very concerned about it but we equally appreciate it is possibly impractical to do it in that way because it might take months," he said.

"There's a possibility of violence breaking out, there's a possibility of investor uncertainty. We are prepared to go along with a sample audit. It will identify if is it an isolated problem, if it is just the 200 we heard about, or if it is a much more pernicious problem."

Provincial co-ordinator for the Good party, Sam Shabane, said they had also raised issues about voters receiving double ballots.

"We also supported the motion that a sample from a particular area or a ward must be taken and an investigation must take place. It will help us to move forward in terms of understanding how deep this has gone," he said. "Now it is no longer in the hands of the management administration; it has to go to the IEC so they also need to come on board."

The committee will meet again at 3pm on Thursday when the IEC is expected to convey some sort of feedback on the issues that were raised.

UDM treasurer Thandi Nontenja said the party was concerned about the "lack of control measures in place".

"When we raised this matter to say what are the control measures besides the ink, the IEC wasn't forthcoming with answers, they were mumbling," she said.

"What irritated us is that they asked that parties come up with the names of people who double voted and the district they voted in."
