South Africa's parliament passed the budget's fiscal framework on Wednesday after weeks of political wrangling, but the future of the coalition government was thrown into doubt after a key coalition partner voted against the measure.

The split over the budget has heightened investor anxiety about a potential fracture in the ruling alliance.
