Princess DianaA horrific set of Princess Diana death photos are going to be shown in public for the first time in a documentary about her fatal 1997 car crash.

The documentary, “Unlawful Killing”, will be shown at the Cannes Film Festival this week and has been backed by actor Keith Allen as well as Mohammed Fayed, whose son Dodi Fayed died in the wreck with Princess Diana.

The 90-minute film features a graphic black and white photo of Princess Diana taken just moments after the Mercedes in which she was riding crashed in a tunnel in Paris.

The Princess Diana death photos have never been publicly seen. Similar photos were shown to an investigative jury following the accident, but Diana’s face had been pixellated.

Friends of the late Princess Diana are sickened by the news that the photo will be shown to the public.

“If this is true, this is absolutely disgusting,” said Rosa Monckton, who went on vacation with Princess Diana just before her death.

“The fact people are trying to make money, which is all that they are doing now, out of her death is quite frankly … words fail me.”

Royal sources also indicate that Diana’s sons were horrified by the news.

Prince William and Prince Harry have said they’ll never publicly speak about their mother’s death because they view it as “the most intensely personal and private aspect of their very public lives.”

“Unlawful Killing” is due to be screened at the Cannes Film Festival on Friday and Fayed is said to be heading to France to help with the launch.
