Nelson Mandela's tribal leaders have been told to prepare for the death of the former president, who remains in hospital unable to breathe without support.
The advice comes after meetings with the family over the past two days. Senior tribal leaders - including Mr Mandela's tribal heir, grandson Mandla Mandela - are expected to visit the hospital for further talks with family members.
Nelson Mandela remains in critical condition, according to the South African government, and multiple sources have confirmed to Sky News that he is no longer able to breathe unassisted.
Police have increased security and blocked the road to traffic outside the rear entrance to the hospital.
