She reportedly has to deal with endless issues regarding other current members of the royal family, but someone else has reportedly caused enough stress for Queen Elizabeth that she has allegedly reached a breaking point.

According to Daily Mail columnist Richard Kay, David Cameron’s recent admission that he sought the Queen’s advice when it came to the 2014 Scottish Referendum has caused her Majesty to rethink the trust and patience she has for political figures, and that the way she views them now is at a “breaking point.”

“The Queen showed signs that there is a breaking point,” he wrote of Buckingham Palace’s response to Cameron’s claim, which came in a documentary to promote his memoir. “The stern rebuke from Buckingham Palace to former Prime Minister David Cameron for speaking out about how he sought her help ahead of the Scottish independence vote in 2014 is the clearest signal that she considers it not only a mere breach of good manners—plenty of politicians, including ministers, have done that in the past—but an abuse of the sacred trust that must exist between Sovereign and Prime Minister.”

“What stung the palace was not just Mr. Cameron’s revelation in a BBC documentary to promote his memoirs that he had asked whether the Queen could ‘raise an eyebrow’ at the prospect of Scotland voting for independence,” he added. “But also the fact that he was making it clear he had used the Queen for his own political purposes, and that she and her advisers thought that was OK.”

The revelation comes at a time where the royal family has been engaged in alleged turmoil, especially as Meghan Markle, the Duchess of Sussex, and Prince Harry, continue to face criticism for their actions, In fact, reports have also claimed that even with Brexit also a contentious topic, the Queen is fine with discussing it, so long as her grandson and his wife are not mentioned, when she goes for horseback rides.

After news broke that the couple was not to be mentioned during the rides, it was also revealed that it isn’t because of their recent PR problems, but in fact, because she doesn’t want to seem like she’s playing favorites by discussing them and not her other relatives.
