Prince William and Kate Middleton's 'secret messaging' at royal events caught on camera

Prince William and Kate Middleton may be two of the most polished senior royals but behind the flawless public appearances lies a surprisingly simple system of secret signals.

One of their most subtle codes was caught on camera during the German state visit on December 3. While viewing rare pieces from the Royal Collection inside Windsor Castle, Princess Kate, 43, was deep in conversation with a curator about the historic artefacts on display.

William appeared engaged, but when he noticed his uncle, the Duke of Edinburgh, approaching, the future king deployed their discreet, time-tested cue.

With a light, guiding hand on the small of Kate’s back, William let his wife know it was time to wrap things up.

Instantly sensing the message, the royal politely closed the conversation, offering a warm “thank you” before the pair moved to the next exhibit.

The quiet exchange, almost imperceptible to the casual observer, is part of the couple’s well-honed communication style during packed royal engagements, allowing them to gracefully keep events flowing without ever breaking their charm or composure.

The Windsor Castle viewing was just one component of the glittering state visit welcoming German President Frank-Walter Steinmeier and First Lady Elke Büdenbender to the UK.

Princess Kate has openly admitted she gets teased for chatting too long during walkabouts.

In the 2016 documentary Queen at Ninety, she said: "I think there is a real art to walkabouts. Everyone teases me in the family that I spend far too long chatting, so I think I've still got to learn a little bit more and pick up a few more tips I suppose."
