Shrien Dewani has always protested his innocence in the case of his wife Anni's murder. The South African authorities claim there is evidence of his involvement but Dewani's supporters have answers for many of the questions raised. Here are some of those questions:
Why did the Dewanis enlist the services of cabbie Zola Tongo instead of using a designated hotel taxi?
A Dewani family spokesman said there was nothing unusual in jumping into a taxi on arrival at a foreign airport. The trip to South Africa had been "very last minute", he said, and the Cape Grace hotel where the couple were staying had just one luxury limousine transfer that had to be booked in advance, costing 600 rand (£56) per journey.
Why was Dewani not harmed in the incident when his wife was driven off and killed?
Dewani's friends say he made every possible effort to save her. They say he was ejected from the cab in a township and did not know where he was. He went knocking on doors and tried to summon help, they said. Dewani is also reported to have said he was dragged out of the vehicle, struggling throughout.
Why did the couple choose to visit Gugulethu, an area known to be unsafe?
The honeymooners were said to have wanted to see the "real" South Africa. It has also been claimed that Tongo suggested he take them to a place where they could see some African dancing and that the couple were lukewarm about going.
Why did CCTV footage show Dewani chatting to Tongo for 13 minutes shortly after his arrival at the Cape Grace hotel?
Dewani's supporters have reportedly claimed he was discussing with the taxi driver his and Mrs Dewani's plans for the next few days.
Why did CCTV footage from the hotel three days after the murder show Tongo apparently receiving a white plastic packet from Dewani, supporting the taxi driver's claim that he was paid for the hit that day?
Friends and relatives of Dewani have pointed out that if he had left the country without settling the taxi fare he would have been accused of running off without paying his debts.
