Prince William's simple public gesture for his wife Kate shows he knows she is the secret to his future regal success, a royal commentator has said.
The Duke and Duchess of Cambridge had been at Westminster Abbey for the annual Commonwealth Day service.
As the royal couple were leaving Westminster Abbey and Kate was shaking hands, it started to rain.
"So what did the future King William IV do? He turned to an aide, got an umbrella and shielded his wife to let her keep going, which she did without missing a beat," Daniela Elser wrote in a piece for news.com.au.
"Now, this is all clearly touching proof that their union is still going gangbusters after more than a decade, three children, three house moves, two dogs and that time Kate flirted with a fringe.
"But what is far more fascinating is what this moment perfectly reveals in only three seconds: that William instinctively understands that Kate is the secret to his future regal success."
Ms Elser said whilst William also does important work, it is Kate who 'dazzles' and who the crowds wait for and read about.
The royal expert said William appears to understand this and has somewhat of a feminist approach.
William and Kate were among the royals at Monday's Commonwealth Day service at Westminster Abbey - an event the Queen was forced to pull out of attending.
After the sweet moment was pointed out on Twitter, royal fans were quick to praise William.
One said: "This makes me smile. Small thoughtful gestures are the building blocks of a deeply loving, stable relationship."
Another wrote: "I love this! I don’t even care that he’s a prince. His devotion is so wonderful!"
While another joked: "Those hats are expensive! He was guarding an investment!"
