Deputy president and ANC chairperson Baleka Mbete is to work at Luthuli House on a full-time basis, party secretary general Gwede Mantashe said on Friday.

"In considering the allocation of responsibilities of the senior leaders of the movement, the officials have decided that Mbete should be deployed to work full-time at ANC headquarters in Johannesburg," Mantashe said in a statement.

The party noted the speculation about where Mbete would be deployed and clarified that she was not sworn in on Wednesday because "consultations about her deployment had not yet been concluded".

The outgoing deputy president in a surprise move remained in her seat after her name was called out as MPs were being sworn in the national assembly on Wednesday.

She was reportedly in the running to continue in her current position.
