Deputy President David Mabuza asked the ANC's top leadership to be relieved of his duties at the Union Buildings, so as to assist in running Luthuli House.
But his request was rebuffed by President Cyril Ramaphosa and his allies, who said it was unnecessary for Mabuza to run the secretary-general's office in the absence of suspended secretary-general Ace Magashule and his deputy, Jessie Duarte, who is off sick.
ANC treasurer-general Paul Mashatile has since been assigned the task, which gives him massive powers in the run-up to the ANC's national elective conference in December.
