Queen Elizabeth passed away on Sept. 8 and her death means that some major royal family secrets will never be exposed.

According to Globe, one of the secrets that the queen took to the grave had to do with what really happened to Princess Diana.

Royal fans know that Prince William and Prince Harry’s died in a car crash in 1997. But the public will never know who was behind her death.

However, there are whispers that the royal family might have been involved. And more specifically, King Charles III may be the one to blame. But as the new monarch, the queen will never destroy her son’s reputation.

Since she’s the only one who knows the truth, royal fans will only be able to speculate as to who was behind Princess Diana’s death for the rest of their lives.

According to the source, the queen also decided to give Camilla the title queen consort to ensure that she would stay silent on Prince Charles’ involvement in Princess Diana’s death.

“It was a ploy to buy the silence of her son’s second wife. The former royal mistress knows where all the bodies are buried,” the source said.

And even though the queen never commented on Prince Harry and Meghan Markle’s antics, the source claimed that she was secretly upset with the couple. However, these are things that she will no longer be able to say after her passing.

“She was disgusted by her grandson turning his back on the family. He was clearly besotted with his ambitious American wife. Her Majesty was also horrified by the couple’s royal-bashing, accusing the family of being cruel, uncaring racists. But she knew all the details and privately held overly ambitious Meghan in contempt,” the source said.

The source also claimed that before the queen’s death, she came very close to stripping Prince Harry and Markle’s royal titles.

However, one should take these claims with a grain of salt because they are not the queen’s secrets that she took to the grave. Rather, these are ongoing speculations concocted by the tabloids for many years.

It’s not true that the queen took her secrets to the grave. And if she did, no one would know what they are because they are her secrets after all.
