As a new full scale inquiry moves closer, the character assassination of the man making the allegations begins.
Scotland Yard has confirmed it is analysing the claims, made in a letter from the mother-in-law of an SAS sniper, but insists there is as yet no new investigation.
It is understood Charles was first informed about the allegations by a Palace aide shortly after the story broke on Saturday. Like Mr Al Fayed, the Royal Family have not commented publicly on the claims.
They are contained in a letter written by the mother-in-law of Soldier N – the housemate of fellow SAS sniper Danny Nightingale
She claims the soldier told his wife the elite unit had “arranged” Diana’s death. The seven-page letter, which makes a number of bizarre and shocking allegations about her son-in-law, was written around the time Soldier N’s 13-year marriage fell apart in September 2011.
