Washington, May 17 (ANI): Lily Allen's filmmaker father Keith Allen has made an explosive documentary on Princess Diana, which alleges the U.K. media conspired with the royal establishment to conceal the truth about her death.

According to him, 'There Are Dark Forces' is a damning indictment of both the British Establishment and the media's reporting methods.

"This is the inquest of the inquest," People quoted him, as saying.

Allen said that while the paparazzi trailing Diana and Dodi Fayed into the Paris traffic tunnel that fateful night have been blamed for the accident, the inquest jury's decision that the tragedy was caused by unidentified "following vehicles" does not confirm it was the fault of photographers.

"It's not about a conspiracy before the crash, but there definitely was a conspiracy after it," he said.

For part of his film, Keith inserted an undercover reporter to tape journalists in the press tent used by the media during the six-month inquest.

"This is an antidote to last year's Oscar-winning movie The Queen, which is the face of the monarchy they want you to see. This shows the Royal Family as they really are," he said. (ANI)
