The ANC will join thousands of Cosatu members when they take to the streets of Johannesburg tomorrow.
The march is part of Cosatu's nationwide protest against rising food, petrol and electricity prices. The South African Communist Party and the South African National Civic Organisation will also join the march.
"We continue to be a liberation movement that is close to the people while also in government," said ANC provincial secretary David Makhura.
Marches have already been held in Durban, Cape Town, Polokwane and other centres.
Cosatu spokesman Patrick Craven said the march would be the same as those that took place in Mpumalanga, Northern Cape and Free State last week.
Businesses and factories in the three provinces ground to a halt as supporters marched through major towns.
Protests will also take place in the Eastern Cape, Limpopo and North West tomorrow.
In Johannesburg, marchers will converge at Beyers Naude Square at 10am and then march to Eskom offices in Braamfontein where a memorandum will be handed over.
The protests will culminate in a national strike on August 6.
