South Africa's coalition government is on shaky ground, with the sharp divisions between its two biggest parties - the African National Congress (ANC) and Democratic Alliance (DA) - exposed in a crucial vote on the national budget.

Leaders of South Africa’s Democratic Alliance will meet to discuss its involvement in the nation’s coalition government after lawmakers passed a budget framework that second-biggest party opposed.

The South African rand extended losses on Wednesday after the Democratic Alliance (DA) party said talks with the African National Congress (ANC) over passing the budget had broken down. The two biggest parties in the ruling coalition have negotiated for weeks to try to reach a deal on the country's contested budget.
