David Cameron accused of hiding SAS involvement in Diana's 'murder plot'

Speculations are rife that Britain's PM, David Cameron, had previously learnt about the SAS's alleged involvement in Princess Diana's death, through a letter, but chose to remain mum about it.

Scotland Yard is currently interrogating Cameron, along with General Sir Peter Wall and Defence Secretary, Philip Hammond, who also received copies of the letter, the Daily Express reported.

According to the UK publication, the wife of the former SAS sniper, known as Soldier N, wrote the concerned letter, claiming that her husband might try to kill her.

Along with her letter, the woman also enclosed copies of a note, which was sent to the SAS's commanding officer in September 2011, containing the original claim linking the SAS to the death of the Princess of Wales.

Even though, Cameron and General Wall replied to the woman, expressing their concerns for her, neither addressed the allegation about the SAS and Diana's death.

The publication further alleges that the woman's letters were handed over to the Met police after the 1997 Paris crash, which killed the Princess, her beau Dodi Fayed, and their driver Henri Paul, but nothing was done about it.
