The state of the city address in Tshwane was delayed on Thursday as ANC members expressed their disapproval of the council’s choice of date for the event.
Executive mayor Solly Msimanga was expected to address councillors during a council meeting held in the city centre.
The African National Congress earlier indicated its disapproval of the Democratic Alliance-led city holding of the event on the day that Solomon Mahlangu was killed.
Its members sang struggle songs about Mahlangu and had a skit inside chambers demonstrating he was killed by the apartheid government.
In March 1978 Mahlangu was found guilty of murder and terrorism. He was sentenced to death by hanging.
The sentence caused an international uproar‚ but the apartheid government went ahead and hanged Mahlangu at Pretoria Central Prison on April 6‚ 1979.
