20:50 - Rival groups of ANC and EFF supporters were singing and dancing close to each other outside a voting station in Pretoria this evening.
The word "voetsak" was prominent in both groups' songs, with only about a metre separating the competing groups.
The groups had congregated near the voting station at the City Hall, along Paul Kruger Street in central Pretoria.
Ivan Madlanga, a supporter of Julius Malema's Economic Freedom Fighters, said he had had a tiring day but "would not leave it for the African National Congress to win".

"It's been going okay, a bit slow. It's not as miraculous as I thought it would be, but it's better than sitting at home doing nothing."
Koena, a Joburg North resident, started setting up at 06:00 - an hour before voting opened - in the hopes of a busy day.
"We've probably sold around 70 rolls, and I'm not sure how many cold drinks we've sold, but it's been okay."

"We hope that we can extend that to every part of the country."
