Pretoria - Deputy President Kgalema Motlanthe cast his vote in Colbyn, Pretoria after joining and following in the queue on Wednesday morning.
"There is no reason for anybody to jump the queue. If I want to be at the head of the queue I should have been here earlier," he told reporters after voting.
"We are all voting as citizens. If there are people already queuing, there is no basis at all to jump the queue."
Motlanthe, 64, is set to retire from active politics, after he declined a nomination to return to Parliament as an ANC MP.
The former student activist and trade unionist said he had voted for the ANC on Wednesday, his last occasion as Deputy President.
"I don't feel any different because I will still be voting in the next elections InshAllah (God willing). I will also be voting in the local government elections next year," he said.
Motlanthe said his tenure in government had been "very hectic".
"As leader of government business I am the link between the executive and parliament. There has been a lot of toing and froing with regards to bills that had to be processed in both houses.
"There was also a lot of work outside parliament - with regards to the work that the executive has to do. I also had to do work with the SA National Aids Council and the Human Resource Development Council, so there has been lots and lots of work," he said.
Several police officers and journalists were at the polling station.
Tshwane Mayor Kgosientso Ramokgopa and Electoral Commission of SA deputy chair Terry Tselane were also at the voting station.
The IEC has said all arrangements were in place at the country's more than 22 000 voting stations.Download the app by visiting one of these stores.
