A British broadcaster will include photos of the 1997 crash in which Princess Diana died despite requests from Princes William and Harry not to do so.
The pictures are of the August 1997 crash site in Paris where the princess, her companion, Dodi Fayed, and their driver were killed.
William's and Harry's private secretary wrote to the broadcaster, saying they believed airing the photos would be a "gross disrespect" to their mother's memory.
In particular, the princes asked Channel 4 to remove several photos of the damaged vehicle with Diana still inside and of a medic treating her.
Julian Bellamy, the head of Channel 4, said the documentary was not intended to distress the royal household and wasn't disrespectful.
