Johannesburg - Economic Freedom Fighters supporters began marching to the SABC on Tuesday with thousands of people making their way down Empire Road.
Five police cars led the march with a sea of red berets behind.
Placards were hoisted high in the air as supporters sang and danced.
Marshalls struggled to contain marchers. Both sides of Empire Road were occupied by marchers, causing a traffic jam.
The march is in protest against the public broadcaster refusing to air the party's election commercial. The SABC claims the advert, which features the slogan “destroy e-tolls physically”, incites violence.
EFF leader Julius Malema walked in front, wearing a red EFF T-shirt, black trousers, red shoes and a red EFF beret.
People watched through the windows of office parks as the marchers passed by. - Sapa
