KEY POINTS:
The leader of South Africa's richest province, Gauteng, resigned yesterday, heightening speculation about a split in the ruling African National Congress.
Mbhazima Shilowa, a supporter of the ousted President Thabo Mbeki, had been provincial Premier of Gauteng, which includes Johannesburg and Pretoria, for almost 10 years.
He said he had quit in protest at the ousting of Mbeki by the party executive.
