The memorial service of Zulu nation interim ruler, Queen Mantfombi Dlamini Zulu, is set to take place on Friday at the Kangela Royal Palace in Nongoma.
Queen Dlamini Zulu, who was 65, died at Johannesburg's Milpark Hospital last week.
Appointed on March 24 to serve as regent of Zulu nation following the death of Zulu King Goowill Zwelithini kaBhekuzulu, one of her tasks was to preside over the coronation of the new King.
Queen Dlamini Zulu, who was King Zwelithini kaBhekuzulu's great wife by virtue of her being the daughter of the late eSwatini King Sobhuza 11, was buried on Thursday morning.
KwaZulu-Natal Premier, Sihle Zikalala, senior members of the eSwatini Royal Family and members of the general public would be amongst the mourners attending Friday's memorial service.
Although the Zulu royal family was on Thursday morning yet to confirm this, there has been speculation that the new King would be announced during Friday's memorial service.
The memorial service takes place as some members of the royal family were challenging the will allegedly left behind by King Zwelthini kaBhekuzulu.
This after the will had stipulated that the estate of the King should be under the control of Queen Dlamini Zulu pending the appointment of the new King.
In their court documents, disgruntled royal family members are claiming that the will, which was presented at a royal family meeting shortly after the King's death, was fake.
