Prince Harry was allowed to avoid drug testers when they suddenly arrived at his Apache helicopter base due to “urgent Palace business”, it is claimed.
The Duke of Sussex has opened up on his drug taking in the past, including trying cocaine and magic mushrooms, in his new memoir which is due out next week.
There have been many leaks as well as the accidental sale of ‘Spare’ in Spain which have provided explosive revelations about his personal life.
And while there is no suggestion that he was taking drugs while in the Army or deliberately missed the test, it has been alleged that he was given permission to not give a urine sample while at RAF Wattisham, in May 2011.
A team is believed to have arrived without any forewarning to the base and Harry was granted permission to leave and head to London on “urgent Palace business” it is alleged.
It is claimed that Harry left in his souped-up Audi A3, having only just returned from London, while all his colleagues were made to give urine samples, reported The Sun.
And the newspaper claims that Harry, who was with 656 Squadron, 4 Regiment Army Air Corps, is thought to be the only one not to be tested.
Squadron Sergeant Major Mark “Oz” Wilson, who was in charge of squadron discipline, reportedly said: “I couldn’t believe Harry was allowed to leave.”
He added: “He had just returned from a period of leave, from being off celebrating Prince William’s wedding. If you miss a test because you are not on camp normally you have to book a test ASAP at the next location you are going to.”
The Duke of Sussex went on to pass his training on Apaches and was deployed in Afghanistan.
His revelation in his memoir that he killed 25 Taliban militants while in Afghanistan has also led to criticism with a former British Army commander saying it is a security threat.
Colonel Richard Kemp also believes that Harry's comments have "undermined" the positive work that he did while in the Army.
The UK's former National Security Advisor also revealed he would have advised Prince Harry against his remarks.
Kim Darroch told Sky News: “Personally if I’d been advising the Prince, I would have advised against the kind of detail he goes into.”
The Mirror has contacted Prince Harry's representatives for comment.
