There is "no credible evidence" to support aclaim that the British military was involved

in the deaths of Princess Diana, her boyfriend and their driver, according to London's Metropolitan Police.
The latest claim, published by Press Association, the Sunday People newspaper and other British media outlets, alleged that members of Britain's elite SAS commando unit were involved in assassinating Diana.The claim appears to have been sent first to military authorities and then to London police by the parents-in-law of a British special forces sniper after his marriage had fallen apart, according to an article on the website of the Sunday People newspaper. It did not offer a source for its reporting, but the paper indicated that the parents were questioning the integrity of the soldier, who had testified in another soldier's court-martial.Sunday People said it had seen a seven-page handwritten letter by the in-laws alleging that the soldier, whom the newspaper did not name, had boasted to his wife that the commando unit was behind the deaths.
