Three men have already been convicted over Anni Dewani's death.
South African Xolile Mngeni was convicted of premeditated murder for shooting her. Prosecutors claimed he was a hitman hired by Shrien Dewani to kill his wife, which Dewani has consistently denied.
Taxi driver Zola Tongo was jailed for 18 years after he admitted his part in the killing and another accomplice, Mziwamadoda Qwabe, also pleaded guilty to murder and was handed a 25-year prison sentence.
