A man accused of shooting dead Anni Dewani while she was on honeymoon in South Africa has pleaded not guilty.
Xolile Mngeni appeared in court in Cape Town after being cleared last week as fit to stand trial despite having surgery for a cancerous brain tumour.
Mngeni denied charges of murder, kidnapping, robbery and illegal possession of a firearm and ammunition at the Cape High Court.
Prosecutors say he was hired by Swede Ms Dewani's British husband Shrien to carry out the killing.
Mngeni was named by a co-accused Mziwamadoda Qwabe as the gunman in the killing of the 28-year-old in November 2010 in a plea bargain that implicated Mr Dewani.
Qwabe, who admitted last week to Ms Dewani's murder, said Mngeni had fired a single fatal shot from the front passenger seat.
He claimed the pair were recruited by the couple's driver to carry out the hit allegedly on businessman Mr Dewani's orders.
Qwabe and the driver Zola Tongo will testify as state witnesses after both entered plea bargains that accused Dewani of orchestrating his wife's death as a botched hijacking.
Qwabe, who was sentenced to 25 years in prison, was the second accused to incriminate Dewani in the killing after Tongo entered his own plea in 2010. He was jailed for 18 years.
Mngeni has a brain tumour which a medical report said will not affect his abilty to take part in proceedings.
He answered not guilty pleas to five charges after entering the court with a walking frame and hiding his face.
Prosecutors are still hoping to put Dewani in the dock in Cape Town after his extradition process was temporarily halted earlier this year, said prosecuting authority spokesman Eric Ntabazalila.
He said: "Our hope was to get all three of them on the stand. We are hopeful that in the end he will come to South Africa and answer to the allegations put to him."
The state is hoping that the trial will be wrapped up in around four weeks, said Mr Ntabazilila.
The High Court in London shelved Dewani's extradition in March, citing health grounds. His lawyers said he suffers from severe post-traumatic stress disorder and depression. He has denied any involvement in the killing.
