The government may raise funding for Eskom by selling its 13.9% stake in Johannesburg-based mobile-phone operator Vodacom Group Ltd., five people familiar with the matter said in February. That's valued at about R30 billion at Vodacom's current share price.

The budget deficit is forecast to drop to 2.5% of gross domestic product by March 2018 from 3.5% last year.
