MILLIONS of people were left heartbroken when the Queen passed away in September 2022 at the age of 96 - and none more so than her close family.
A royal writer has claimed that the beloved monarch left a “secret letter” for son King Charles, and its contents will remain private.
Robert Hardman, author of Charles III, revealed to that the late Queen left the poignant memento in her red box, which she used for important documents.
The royal commentator said: “The thing that absolutely put the hairs on the back of my neck was when I heard about it was her last red box.
“She'd had a red box brought to her every single day of her life as Queen.
“She was only ever allowed two days off, her birthday and Christmas Day.
“Other than that her red box, every day, was full of papers and stuff to be dealt with.
“And right at the end, you know, they opened up her last red box, it's there in her room after she's died and there's a letter to the Prince of Wales.
“We'll probably never know what was in it.”
He claimed that a letter was also left for the Queen’s private secretary Sir Edward Young.

“That's why she was so keen to be on her feet and looking the part in that first photo shoot with that final photograph because you know, all summer there hadn't really been a Government to speak of.
“Her absolutely number one duty as a constitutional monarch is to ensure the good governance of the country.
“And so she wanted to appoint Liz Truss, and get that done.
“And she was very buoyed up having done that was a weight off her mind.”
King Charles has bravely revealed he has been diagnosed with cancer - just weeks after he underwent prostate treatment.
All that is known about the King’s condition is that he does not have prostate cancer.
No further details about what stage the cancer is or the prognosis has been given, but Charles is reported to be “positive” about his treatment and looking forward to being able to return to full public duties as soon as possible.
Prince William and Harry - as well as Princess Anne, the Duke of York, and the Duke of Edinburgh - were all told personally of the news.
Prince Harry will fly to the UK to support his dad.
Robert also spoke of the decision of the king to reveal personal details of his health issues.
He said: “I think we certainly know more than we would have known in the past. “Just a few years ago, you would not have seen the words enlarged prostate in a Palace statement.
“But the King takes the view that the public has a right to know certain things.
“They don't have a right to know everything.
