Johannesburg - The ANC's Top six will not be participating in the build-up programmes ahead of the launch of the Mandela Centenary celebrations due to "urgent meetings", it emerged on Friday. 

Instead, the party's National Executive Committee (NEC) members would be the ones participating in Friday and Saturday's planned activities. 

Initially, only ANC president Cyril Ramaphosa and National Chairperson Gwede Mantashe were confirmed to no longer be taking part due to other other engagements. 

Ramaphosa's cancellation was due to "other pressing commitments" while Mantashe had been "deployed to the Mpumalanga province".

On Friday however, ANC Western Cape Provincial Secretary Faiez Jacobs confirmed to eNCA that the rest of the Top six would also no longer be taking part in activities.
