Kate Middleton has upstaged sister-in-law Meghan Markle in a royal power play set to "change the crown forever", claims an expert.
Commentator Daniela Elser said the Duchess of Cambridge has been "nailing the social media game" while the world is distracted by "the Harry and Meghan Show".
She pointed to a video shared on Prince William and Kate's Kensington Palace social media accounts over the weekend marking Anzac Day as a key example.
The footage included the Duke writing letters to the Australian and New Zealand high commissioners on the national day of remembrance for both nations.
Ms Elser said the clip, which also featured an "unseen flunkie zipped across London to deliver the missives along with homemade Anzac biscuits", showcased how "quietly radical" the Duchess can be.
Writing for news.com.au, she said: "It was indisputable proof of something that has become increasingly apparent of late: Kate is simply nailing the social media game right now.

"See, while royal news over the last year has nearly been wholly consumed by the ongoing Sussex melodrama, all TV tears, pouting, posturing and eye-popping business deals, something very interesting has been going on back in the UK.
"That is, while the eyes of the world were, by and large, glued to the Harry and Meghan Show, Kate has been revolutionising the royal social media game."
Ms Elser also highlighted a post shared by Kensington Royal at Easter as another "case in point".
Rather than the obvious imagery associated with the time of year, the Cambridges instead went with a "cheeky" video of a chocolate egg being smashed in reverse, she said.
The commentator added that Kate's skills as an amateur photographer have also helped in the couple's "social media transformation".
And are key going forward as they oversee a "significant intellectual shift" in the Firm's image as they prepare to take charge in the years to come.
Ms Elser added it is "openness and realness" and "at times tongue-in-cheek" humour that are the perfect way to ensure the monarchy continues to engage with the people.
