The eldest daughter of Angola’s former President José Eduardo dos Santos has been sacked as chair of the board of the state-owned oil firm Sonangol.
A presidential decree on Wednesday said Ms Isabel dos Santos had been replaced by Mr Carlos Saturnino.
Ms dos Santos was appointed to chair the Sonangol board of directors by her father in June 2016.
She was tasked with the responsibility of ensuring the restructuring of the state company.
New President João Lourenço took over from dos Santos in August, following an election, marking the end of a 38-year reign.
His sacking of the predecessor’s daughter is seen as a powerful message asserting his authority.
