Royal expert Duncan Larcombe said on Friday that it’s understandable why Camilla would have been “miffed” over the photos. He told The Sun Online: “The ‘men in grey suits’ are at pains to avoid diary clashes and the prospect of one member of the family outshining the other on the same day. Camilla would be justified at being miffed to say the least. But as Harry and Meghan continue their work without any regard for the rest of the work of the Royal family, these kinds of ‘clashes’ are inevitable.”

The post – which is now unavailable since Harry and Meghan closed the account – was captioned: “Yesterday, The Duchess of Sussex, Royal patron of the National Theatre, visited the Immersive Storytelling Studio in London, where emerging technology like Virtual Reality is being used to develop new forms of emotive storytelling. “Recently, The Duke and Duchess of Sussex also visited Stanford University where part of their learning journey included a virtual reality presentation that allows the user to experience life through another person’s point of view.

“The goal of this method of virtual reality is to enable us to better connect and empathise with each other as people, regardless of race, age or nationality. The Duchess is pictured here with Nubiya Brandon and her hologram, featured in the National’s exhibition ‘All Kinds of Limbo’, which is currently being presented at the Tate Modern.”

Despite attracting more than 500,000 “likes” at the time, the post drew a mixed response from followers. One blasted the duchess for having “a bad vibe” while others described her as “cringey”. The incident came a time when Harry and Meghan had returned to the UK for a string of engagements before officially stepping down as working royals.
