BBC News reports that Kenton is not only “very sad” by the Palace’s decision but also taken aback, saying that she found the removal of the brand’s warrant “unbelievable” and that her book contained “nothing” to “be upset about”.

“I’m very sad Buckingham Palace took exception to the story - it’s a kind and gentle story about what went on in my life,” she said.

Kenton continued, “I only ever said I went there, not what happened. I have never, ever spoken about what I do there with her, or the Queen Mother or Princess Margaret.”

“I think it’s unbelievable. It’s just upsetting at the end of my life, but what can I do. I can’t fight with Buckingham Palace and I wouldn’t want to, but it’s hard.”

Elle reports that Kenton talks about fittings with the Queen in the book and describes how her Majesty’s corgis would be present while she was half dressed. She also spoke about William and Harry as teenagers, reminiscing that their mother, Princess Diana, would let them pin pictures of underwear models to their walls while boarding at prestigious school, Eton College.

According to BBC News Kenton admitted she didn’t submit the book to the Palace for approval before publishing because she didn’t think anything “would be required”.

Kenton said, “I’ve been honourable throughout my life - it’s unbelievable they don’t like the book, there’s nothing in it that they could remotely be upset about.
