President Jacob Zuma is on Friday evening expected to address the nation after the Constitutional Court ruling over upgrades at his Nkandla homestead.
The Presidency issued an alert stating that the president was to address the nation at 19:00.
The ANC was also expected to hold a press briefing at 20:00.
Further details were not immediately available.
On Thursday, the Constitutional Court had ruled that the president should adhere to the remedial actions of the public protector and pay back tax payers funds which were used for non-security upgrades worth millions at his Nkandla home.
The court further ruled that Zuma and the National Assembly had violated the Constitution by ignoring the public protector’s report.
Since the ruling, opposition parties have called for Zuma to step down.
