Shrien Dewani's mental health will be the focus of scrutiny when he arrives in South Africa to face charges of conspiracy and murdering his wife Anni Dewani.
The millionaire care home owner has denied any involvement in the killing of his wife in a crime-ridden suburb of Cape Town during their honeymoon, claiming they were victims of a car-jacking.
However, three men who were jailed for the murder stated they were offered £1,400 by Dewani to stage the hijacking in Gugulethu township near Cape Town in 2010.
His extradition has been delayed for three-and-a-half years midst claims that the 33-year-old is 'too ill to be extradited.'
Dewani's lawyers claimed he is a high suicide risk as he suffers from post-traumatic stress disorder and depression.
However, Anni's father Vinod Hindocha has said he believes that the suspect in his daughter's killing is faking his mental state.
"I have always queried in my mind just how mentally ill he was," said Hindocha. "Just how long can post-traumatic stress last is a question that has been in and out of my mind continually.
"Shrien was perfectly well during the time he travelled back from Cape Town with Anni's body and he was arrested soon after."
"It has been nothing short of torture for us. An extradition order should not take so long," added Hindocha.
Dewani has spent the past 18 months living in a camper van in the grounds of Blaise View mental health hospital near Bristol and has been allowed to visit his family home nearby during the day.
He will now be transferred to Valkenberg, a South African psychiatric hospital, which houses some of South Africa's most notorious killers and rapists.
His condition will be monitored by investigators 24 hours a day to determine whether he is fit for trial and fully understands the indictment for murder.
A report based on their findings will be submitted to the court within 30 days and his hospitalisation period could be extended or a court date set.
Experts said that if Dewani is indeed faking his condition, he will be exposed.
"Any notion that he has been faking illness for the past few years will be minutely examined. Medication will be at a minimum so as not to mask his true condition.
"Dewani will be seen regularly by consultants but it is when he is back in the ward that he will let his guard down and that is often where we get our most useful insights. His attitude to other patients and the staff, even domestic workers, will be crucial to our observation methods."
A medical source at the hospital added: "Frankly it is impossible for him to be genuinely ill for that period, we have never experienced that."
It has also been reported that Dewani will be afforded special privileges including a private room, specially prepared meals by his own chef, with opportunities to participate in group activities such as group therapy, cooking and sewing classes.
His lawyers assert that these privileges are necessary to uphold his human rights.
Meanwhile, the family of Anni Dewani have backed plans to televise the trial in South Africa.
Vinod Hindocha said: "She was my daughter, certainly, but since she was shot she has become the daughter of the world. I have been asked if I have any objection and my answer is that I do not. I feel the world wants to know what happened to Anni.
"Judging by the thousands of letters from across the world we have received from people we have never met, there is a great amount of interest."
The decision to broadcast Dewani's hearing will be decided by the judge. Several TV and radio networks have sent applications to the Judge President, arguing there is a valid public interest in live coverage.
Dewani will be escorted by two senior officials, a doctor and a nurse to London's Heathrow Airport, where he will fly directly to Cape Town.
He will be met by officers from the elite Hawks police unit and he will be escorted to Cape Town's High Court to be formally charged with murder.
After the conditions of his bail are determined he will be transported directly to Valkenberg.
Dewani denies any involvement in the killing of his wife Anni.
