Dr Nkosazana Dlamini Zuma received 123 nominations while her rival Deputy President Cyril Ramaphosa clinched 117.
Keeping to the Dlamini-Zuma slate, the province voted for David Mabuza as deputy president (434); Nathi Mthethwa as national chairperson (358); Ace Magashule as secretary general (410); Jessie Duarte as deputy secretary general (357) and Nomvula Mokonyane as treasurer general although Maite Nkoana-Mashabane was slated for the position of treasurer general.
The South African rand edged up on Tuesday ahead of third-quarter growth data, holding on to gains made in the previous session on investor hopes of a reform-friendly outcome at the ruling African National Congress (ANC) leadership conference. Provincial executive committees also vote, as do national executive committee members.
The election has divided the 105-year-old ANC like never before and pitted Ramaphosa and party veterans against Zuma, who's been mired in allegations that he allowed members of the Gupta family, his son's business partners, to influence cabinet appointments and the awarding of state contracts.
There's still no clarity, however, on exactly who most delegates in Mpumalanga are supporting after the word "unity" appeared on most ballot papers during the provincial general council.

"We must put the unity of the organisation first. The work that is there is to try and convert "Unity" into names of human beings".
Mantashe says delegates will only have a choice between officially nominated candidates.
