Linking the Queen’s dedication to her profound bond with King Charles, Jennie mentioned: “I think part of it is because she so much wants the man she loves to be proud of her, and to pull her weight in their partnership.”

Notably, she also underscored the significance of Duchess Camilla gaining acceptance from a public that once detested her.

“It must be so gratifying to have earned widespread approval – even affection – from a public who once ganged up against her as the ‘marriage breaker’ and the ‘other woman’ who made Diana so unhappy,” Jennie added.

In a rather unexpected revelation, the former BBC star confessed that Princess Diana had once predicted this level of devotion and commitment.

She said: “I think Diana was absolutely right to tell me that Camilla was ‘loyal’ and that Charles’ love for Camilla was stronger than any marriage he might ever have made.”

Reflecting on the Queen’s journey since she stepped into the Royal limelight, Jennie complimented her growth in confidence, shrewdly remarking: “What a contrast to those early days when she looked and sounded so very nervous if she had to speak in public. Now she is assured, confident and comfortable in her new and very demanding role.”
