He has been fighting extradition to stand trial in Cape Town for over two years. The BBC One Panorama programme in the United Kingdom planned to air a documentary on Thursday looking at the criminal case against Dewani, according to its website. The programme, titled "The Honeymoon Murder: Who killed Anni?" claimed to have obtained "secret police files" and commissioned forensic experts to review all the evidence. According to the online preview, the experts plan to expose "fundamental mistakes" in the police investigation and the interpretation of forensic evidence. Chief Magistrate Howard Riddle ruled in 2011 that Dewani should be extradited but he successfully appealed against this order, on mental health grounds. The British Press Association reported in July that Riddle had ordered for Dewani to be extradited on the basis of a slow but steady recovery. "It may be a long time before Mr Dewani is fit to plead, but he may be closer to that point," he was quoted as saying. "It is not impossible that if returned now, then after a reasonable period of further treatment and assessment he will be found fit to plead and a trial can take place." Agence France Press reported last month that Dewani launched an attempt to take his extradition case to the Supreme Court, arguing his mental health was too fragile.
