Three men have been convicted over Mrs Dewani's death.
Last year, South African Xolile Mngeni was convicted of premeditated murder for shooting her. Prosecutors claimed that he was a hitman hired by Dewani to kill his wife, something that Dewani has consistently denied.
Taxi driver Zola Tongo was jailed for 18 years after he admitted his part in the killing.
Another accomplice, Mziwamadoda Qwabe, also pleaded guilty to murder and was handed a 25-year prison sentence.
Lawyers acting for honeymoon murder suspect Shrien Dewani intend to appeal against today's ruling that he should be extradited to South Africa to face trial over his wife's death, a spokesman for his family has said.
Anni Dewani's family have said they are "satisfied" with a court ruling that her husband Shrien should be extradited to South Africa to face trial for orchestrating her murder.
Anni's sister Ami Denborg said: "It's still a long way to the answers that we are looking for and we don't want to forget Anni in this. For us it's all about Anni, it's all about finding out what happened to her."
She added that they were hoping for a speedy recovery for Dewani so he can be fit to plead.
Shrien Dewani should be extradited to South Africa where he is accused of orchestrating the death of his wife, a hearing at Westminster Magistrates' Court has ruled.
Anni Dewani, 28, was shot as the couple travelled in a taxi on the outskirts of Cape Town in November 2010.
Chief Magistrate Howard Riddle said that the 33-year old businessman should return to the country, despite arguments by his defence team that he could suffer setbacks in his mental health if sent back now.
They argued that the decision should be delayed by six months.
Mrs Dewani's relatives attended the hearing and wore photographs of her pinned to their clothes, decorated with pink ribbons.
Bristol businessman Shrien Dewani will find out today whether he will be extradited to South Africa to face trial over the murder of his wife.
Mr Dewani is accused of arranging her murder on their honeymoon in Cape Town in 2010. His lawyers say he is suffering from depression and post-traumatic stress disorder and should not face trial abroad.
