While Prince William beams as a proud new father, a new theory in the death of Princess Diana surfaces, raising questions. INSIDE EDITION reports.
New claims of a plot to murder Princess Diana are causing an uproar.
A new investigation was triggered by a former soldier of Britain's Special Forces, the SAS who boasted to his ex-wife that his unit murdered the princess.
A Scotland Yard spokesman confirmed they have launched an investigation: "We are assessing its relevance and credibility."
The news is being met with worldwide skepticism.
On Good Morning America, Dan Abrams said, "This accusatory letter cane from the estranged parents of the wife of a former intelligence operative. Talk about hearsay, upon hearsay, upon hearsay."
Princess Diana was killed in a car crash in Paris in 1997. Security camera video was taken minutes before as she left the Ritz Hotel. Official investigators blame the driver, who was said to be drunk and paparazzi who were chasing her car.
Author Alan Power claims in a new book, The Princess Diana Conspiracy that Diana was assassinated.
INSIDE EDITION's Megan Alexander asked Power, "You believe Princess Diana was murdered?"
"She undoubtedly was," said Power. "It had to be assassins. It was murder."
He says British Intelligence officers blinded the driver with a powerful strobe light. The motive: Diana was planning to go public with Prince Charles' alleged sexual peccadilos and move to the USA with her sons, William and Harry.
"The children would have been brought up outside of the control of the monarchy," said Power.
Prince William isn't commenting on the new claims, but he is talking about life as a new dad.
"The last few weeks for me have been just a very different emotional experience, something I never thought I would feel myself," said Prince William.
Speaking out for the first time since the birth of baby Prince George, William told CNN the little one is a rascal and keeps him and Kate up at night.
"As a few new fathers might know, I'm actually quite looking forward to going back to work," said William.
"To get some sleep?" asked a reporter.
"To get some sleep, exactly, yeah," said William.
