The National Treasury has submitted a report to the Constitutional Court on how much President Jacob 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.
