South Africa’s ruling ANC party faces its greatest post-apartheid challenge, with the rise of a breakaway party determined to bury its all-powerful rival. The new Congress of the People elected the former South African Defence Minister Mosiuoa Lekota as its leader, and said it would campaign on a pro-business platfrom.Lekota is close to former president Thabo Mbeki, and quit the ANC when it forced Mbeki to resign. He hopes to capitalise on growing anxiety among middle class South Africans over the ANC’s unchallenged hold on South Africa. The ANC led the fight against white rule in Souoth Africa, and its new leader Jacob Zuma is the front-runner to become the country’s next president. But the deep split in ANC ranks may make that less of a foregone conclusion.
