The Queen often walks around the grounds of Balmoral completely unnoticed because she doesn’t wear her tiara, according to a former royal protection officer.

Speaking to The Times, Richard Griffin said that she is so unrecognisable, a group of tourists once had a long chat with her, not knowing that they were speaking to The Monarch.

However, Mr Griffin said that The Queen did not want to blow her cover when talking to the tourists, so she played along.

The American tourists asked The Queen whether she lives locally. She simply responded that she lived nearby, not giving away that the lived in the huge Balmoral Castle they were stood beside.

The tourists also asked if she had met the Queen, whereby she pointed to her companion and said: “No, but he has.”

Her Majesty was not recognisable in her headscarf and wellington boots according to the former protection officer. The public are used to seeing her in a bright array of colours with large hats.

This news comes on the same day a soldier made another revelation about The Queen. He said that she often used to taste soldiers’ packed lunches before they ate them, to make sure they were ‘being looked after properly’.

The soldier said: “The Royal Family were so much fun to work for, they made all the soldiers feel at ease.

“One of Her Majesty’s priorities was looking after the welfare of the soldiers who were responsible for providing support for all events.

“She often tasted our packed lunches to check we were being properly looked after before we went out on hunting or fishing trips. She would come to the kitchen and inspect the sandwiches.

“Most were up to scratch, but if they weren’t, they’d be sent back.”
