Queen Elizabeth II has faced several challenges over the years. With her advancing age, a royal expert has claimed that Princess Diana would have been “sad” for her.

Speaking to the Mirror, Ingrid Seward shared some of her thoughts about the late royal. She stated that if the Princess of Wales was still alive, she would be concerned about the British Monarch, considering all the strains of her age on top of all the controversies and challenges of the monarchy today.

The outlet quoted the editor-in-chief of the “Majesty” magazine, claiming, “Diana would have been sad the Queen was having so many troubles at her great age.”

But, despite this, Seward noted that the late royal “would have known however frail [the Queen] might appear, [she] can deal with anything.”

Much has been said about the relationship between Princess Diana and Queen Elizabeth II. But, no confirmations have surfaced detailing how close they were in the past.

Some reports are said to have claimed, though, that the British Monarch was “fond” of her eldest child’s first wife. Moreover, the late royal reportedly once stated, as well, that she had the “best mother-in-law in the world.”

Elsewhere in the exchange, Ingrid Seward shared with the outlet what Princess Diana would have felt about her two sons, Prince William and Prince Harry today. She recalled that the late royal was “deeply proud of both of them.”

The royal expert said the Princess of Wales previously decided to settle in the United States. Accordingly, she believes that the royal would be “thrilled” about her youngest son realizing “her dream for himself and [doing] just that.”

As for the Duke of Cambridge, the late royal reportedly knew his “destiny was the monarchy.” So, it is said that she “would have been happy he has come to terms with his tough role.”

The latest claims about Princess Diana and Queen Elizabeth II come as news broke that the latter will not be able to travel to London next Tuesday.

Officials confirmed that the British Monarch will receive Boris Johnson and his successor in Balmoral instead of Buckingham Palace, according to MailOnline.

The outlet noted that the Queen traditionally holds audiences with the outgoing and incoming premiers at the Palace. This causes the “ceremony” on September 6 to become historic as it will mark the first time a Prime Minister has officially stepped down or been appointed far away from Buckingham Palace in the monarch’s seven-decade reign.
