Rustenburg - North West premier designate Professor Job Mokgoro was due to be elected and sworn in as provincial premier on Friday.
He was sworn in as a Member of the Provincial Legislature (MPL) on Thursday night.
African National Congress (ANC) secretary-general Ace Magashule on Thursday officially announced Mokgoro, 70, as the new North West premier candidate, following the resignation of Supra Mahumapelo from the post on May 23.
Despite being described as an excellent administrator, the Economic Freedom Fighters (EFF) in North West came out with guns blazing, rejecting Mokgoro as the new premier.
"Professor Job Mokgoro is nothing but an extension of the corrupt cabal of the disgraced Supra Mahumapelo who was forced out of office after the emergency of a series of corruption scandals in his administration.
