This is the sweet moment Kate strokes Charlotte’s hair and guides her forward in behind-the-scenes footage of the Waleses at Trooping the Colour – after the Princess of Wales dazzled in her first public appearance since her cancer diagnosis.

In a gentle scene, the older siblings Princess Charlotte, 9, and Prince George, 10, can be seen waiting nervously in the doorway as Kate quietly smooths her daughter’s locks.

Charlotte can be seen anxiously moving around as she clasps her hands in front of her, and she quietly says a few words to her mother while watching the carriage approach.

Then, as the royals walk in synchronized steps towards their seats Charlotte seems to take a deep breath, while Kate tenderly takes her hand.

And steadied by her family, as she waits in the carriage to set off, she can be seen smiling happily through the window as they chat together in the coach.

Louis – who appears to have no such nerves – is laid back as he leans casually against the wall, wearing shorts and a smart jacket.
