Meghan and her husband, Prince Harry, are in the UK for their final engagements before stepping down as senior royals. According to The Mirror Camilla was left “very upset” after Meghan upstaged her domestic violence speech.
The paper reports this violated an agreement to avoid doing anything that could distract from the address.
Camilla is the second wife of Prince Charles, the next in line to the throne.
The Mirror reports a royal insider as saying: “Camilla’s work is very important to her and her decision to highlight the scourge of domestic violence at the 10th anniversary of Women of the World was a carefully thought-out plan.
“Over the last four years she has worked tirelessly, mostly behind the scenes but to great effect, to use her platform and personal experiences to highlight the issue and help sufferers.
“Of course it was known Harry and Meghan would be doing engagements this week, some privately, but everyone was in agreement that Camilla’s speech should take precedence.
“Unfortunately some people had other ideas.”
As insider claimed Meghan had “refused to listen” to staff who warned against the move.
On Thursday Meghan visited the National Theatre, of which she is patron.
Camilla used her address at the Women of the World Festival in London to speak out over domestic violence.
She commented: “On this tenth anniversary, as WOW’s proud president, it’s a huge pleasure to be here today.
“But I’m also here as a woman in her 70s, who, as a somewhat ancient technophobe, is not always familiar with some of the jargon younger people use today, but I do know about hashtags.
“And now I am using my very first one: #everyonesproblem.
“Domestic abuse is everyone’s problem and the solution must be too.
“I find it almost impossible to think any friend of mine might be living under that horrific threat, without my knowing it, but that is the power of coercive control and violence in the home.”
