He also acknowledged the disunity within the ANC but said Mr Mandela's centenary year "offers us a new beginning".
The NEC meeting in the Pretoria, the capital, was convened after Zuma defied calls by the party's top leadership to step down, according to four people familiar with the matter. "It is therefore important that we manage the discussions that are now underway with care and objective, ensuring that we place the interests of South Africa first".

In his speech, the deputy president said the government will wage a "relentless war against corruption and mismanagement of the resources of our country" and that the justice system will punish the guilty. Many former supporters in the ANC, the party of Mandela, want him to resign immediately so that they can try to recover the confidence of alienated voters.
The African National Congress's top six officials had been called into an urgent meeting with Zuma, Johannesburg-based broadcaster eNCA reported.

"It is an ideal which I hope to live for and to achieve". He died in 2013 at the age of 95.
"Comrades, let us now all disperse in an orderly fashion, " he said.
