“One of the worst experiences ever,” said Vavi, who also went to the Union Buildings on Wednesday.
He was accompanied by former trade unionist Jay Naidoo.
Vavi and Naidoo seemed overwhelmed, tired and sad. Vavi was unable to comment further.
The crowd cheered when they saw Vavi, shouting “Viva Vavi, viva”.
Tshwane city mayor Kgosientsho Ramokgopa was also walking around talking to people.
