South Africa's ruling African National Congress (ANC) is set to announce its new leader on Monday, with the winner likely to be the country's next president.
The announcement is expected around midday London time and comes after the party's five-yearly national conference which began Saturday.
The two frontrunners are current President Jacob Zuma's ex-wife Nkosazana Dlamini-Zuma (NDZ) and Deputy President Cyril Ramaphosa, a businessman and former trade union leader who is also one of the country's richest men.
While polls have placed Ramaphosa ahead for the vote in Johannesburg, Martin Roberts, deputy head of Africa at analysis firm IHS Markit, suggested to CNBC that Zuma could use his influence — be it financially or legally — to ensure that NDZ wins the leadership. She is viewed as a proxy for the incumbent president, though she has insisted that she is standing as a candidate in her own right.
