Ramaphosa announced that he would be making changes to his cabinet and would make an official announcement this afternoon.
His reshuffle comes after the resignation of home affairs minister Malusi Gigaba left two vacancies in his cabinet.
"The postponement is due to other political developments primarily the expected announcement on cabinet reshuffle," said ANC spokesperson, Pule Mabe.
Mabe said the party would only hold its press briefing on the Zondo commission on Friday.
