>> South Africa's ruling African national congress will pick a new leader this weekend to replace Jacob Zuma. The stakes are high. The winner is likely to follow Zuma's footsteps to become the country's next president. As Reuters Ed Stoddard reports the corruption allegations that have plagued Zuma's tenure and which he denies will likely influence the vote.
>> Zuma's corruption scandals which have actually been going on for decades, are constantly in the media here, are constant source of conversation, not just around middle class dining tables, but also In townships, on farms, in rural areas. If you're driving a taxi here, you speak to a taxi driver.
They will immediately begin talking about Zuma and his numerous corruption scandals. So this reigned very heavily on the months of the election. And it will have a significant impact on the voting this weekend.>> One front runner is deputy president Cyril Ramaphosa, a former trade union leader and one of South Africa's richest people.
He's seen as investor friendly and has vowed to tackle corruption. And then there's Zuma's choice, his ex wife Nkosazana Dlamini Zuma, a former minister and chair of the African Union Commission. She promises to improve the lot of the black majority. Political uncertainty over corruption and the ANC race have hit South Africa's credit rating and thrown more than a century old ANC into crisis.
>> The new leader of the ANC will also need to bring policies that will help to revive economic growth. That could be a very tall order, for example, Ramaphosa, he has to please his twin basis which are business and unions, and so whoever takes over will have a difficult tightrope to walk to revive the fortunes of the party.
>> All seven candidates have promised to accept the outcomes of this weekend's vote to avoid further weakening the ANC before national elections to replace Zuma in 2019.
