The Presidency will study the National Treasury report which found that President Jacob Zuma should pay back R7.8-million for non-security upgrades in his Nkandla homestead, it said on Monday evening.

Presidency spokesperson Dr Bongani Ngqulunga said, "The Presidency has this late afternoon, June 27, received the report that the National Treasury submitted to the Constitutional Court. The Presidency is studying the report and will comment on it thereafter," it said.

The National Treasury submitted a report to the Constitutional Court on how much Zuma must pay for non-security upgrades at his Nkandla homestead.

"All queries regarding the matter should be directed to the Court," the National Treasury said in a statement.

It was given 60 days by the Constitutional Court to calculate a reasonable cost.

According to the report, released to the media by the Constitutional Court, the total amount calculated was R7.8-million.

"As a consequence, the reasonable percentage of the estimated costs of the five measures that the President would have to pay personally would be 87.94%.  This percentage corresponds to R7 814 155 as at June 2009," read the report.
