Polokwane - The ANC's deputy president, Kgalema Motlanthe, on Saturday warned ANC members against voting according to slates.
"The emergence of slates within our organisational culture and the processes represent the worst form of corruption of the spirit, character and vision of the organisation," Motlanthe told delegates at the provincial elective conference in Polokwane.
"The time has come for all of us in the ANC to condemn the slate culture to the dustbin of history."
Motlanthe said members must stand up and speak against "this demon" that seems to destabilise, demoralise and emasculate the ANC of all its historical achievements.
"Stealing away the voice of members through slates, buying of votes and treating the ordinary membership as voting fodder...serves no other purpose than to corrupt the organisation."
Motlanthe said the issue of slates was one of the issues that threaten to weaken the ANC in the next 100 years.
The practice of slates represent a deformed character of the organisation, he said.
President Jacob Zuma, who is also president of the ANC, had been expected to address the delegates but the ANC had replaced him with Motlanthe.
This was reportedly to save him embarrassment after it was learnt that delegates loyal to ANC provincial chairperson Cassel Mathale were unhappy with him and had planned to boo him, especially after his decision to put five of Limpopo's department's under administration.
