South Africa's rand weakened in early trading on Friday (July 1), a day after hitting a 20-month low on the back of extended power cuts by struggling state utility Eskom, and fears over the risk of a global recession.

De Beers Group and Botswana's government will extend an agreement for the sale of rough diamonds from their Debswana joint venture by a year, De Beers said on Wednesday (June 29).

Hundreds of Ghanaians took to the streets on Tuesday (June 28) and Wednesday to protest over spiraling inflation and other economic woes.
