Experts agree that Kate Middleton, who just turned 40, is at the peak of her career. She has gained confidence, she has taken the time to carefully choose the causes she supports, and she is also widely loved by the public and an elegant symbol of the farm.

Thanks to these qualities, royal insider Patrick Jeffson, who previously worked for Princess Diana, believes that the Duchess of Cambridge is now the single best asset to the royal family.

"As the Prince Andrew scandal has shown, the monarchy is in desperate need of a reassuringly unconventional royal performer," Jeffson tells Page Six. It is no exaggeration to say that the future of the House of Windsor is in her hands." [Unlike business, political, or media stardom, the royal family is a lifetime employer, and its time horizon is limitless. Princess Catherine has mastered that long game, and that is a very important achievement." [For royal writer Bethan Holt, it is no coincidence that the Cambridges have been in the limelight so much lately. Holt explains, "Prince Charles and his wife Camilla seem to have no global influence, and there seems to be an absolute campaign to make William and Kate the family's global stars." It seems that the entire royal family is trying to lift up the Cambridges."

It makes sense: despite rumors of an affair that has antagonized some royal fans, Prince William and his wife are still popular with the public these days. While younger royals such as Princess Eugenie and Princess Beatrice are also well-liked, the Cambridges, as the future king and queen, are the overwhelming favorites among the more senior royals.

Many do not love the fact that Prince Charles had an affair with Princess Diana and his current wife Camilla Parker-Bowles. While Meghan Markle and Prince Harry have many supporters after their departure from royal life, they also have many opponents. And Prince Andreu has been accused of sexual abuse.

The Duke and Duchess of Cambridge, on the other hand, are often seen as moral, approachable, friendly, and adaptable to the times. They are, so to speak, worthy of the crown.
