Where is the money going to come from?
Already facing falling tax revenues, the government purse is under new pressure from President Jacob Zuma's creation of new departments and the splitting of departmental functions.

Budget processes are still under way, but billions of rands will be needed to accommodate the new departments of economic development and rural development and the splitting of the education and minerals and energy portfolios.

Government departments are scrambling to get their wish lists together for the coming budget votes in Parliament, when ministers will present the priorities and proposed budgets of their departments.

Starting from scratch, new departments will have to assemble strategic plans and budgets.

The treasury was officially informed of the new structure of government only when President Jacob Zuma announced his new Cabinet. It may need to rejig the budget and a Special Appropriations Bill may be on the cards, requiring Minister of Finance Pravin Gordhan to ask Parliament for approval for additional spending.
