Shrien Dewani: Max Clifford on 'heinous crime' accusation
20 February 2011 Last updated at 17:12 GMT
Max Clifford said the claims made by South Africa's Director of Public Prosecutions are "frightening", amid claims of witnesses being intimidated by police.
Prosecutor Menzi Semelani accused Shrien Dewani of ordering his new wife's murder and of committing a "heinous crime" in an interview on South African television.
South African authorities want Mr Dewani to return to stand trial for the alleged contract killing of wife, Anni.
Mr Dewani is currently on bail in the UK, but may face extradition. He denies any involvement in the crime.
Max Clifford said the comments suggest Mr Dewani would not get a fair trial if he was extradited to South Africa.
