The Sussexes' silence over the announcement of Camilla's becoming Britain's next Queen is a "deliberate insult" and shows the couple "never liked her", a royal expert has claimed.
Recently, the Queen backed Camilla to take the Queen Consort title when her husband Prince Charles is King.
In an extraordinary statement on the eve of her Platinum Jubilee, the Queen expressed her wish for Camilla to be known as Queen Consort when Prince Charles takes the throne.
For years insiders were sure Camilla would take the title Princess Consort instead - although there had been speculation that Charles wanted his wife to be his Queen.
In a message to the nation, the Queen wrote: “When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me.
“And it is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service.”
In reply, Charles paid tribute to his "inspiring" mother in a moving statement, admitting he's "deeply conscious" of her wish for Camilla to become his Queen Consort when he takes the throne.
However, as many applauded the move, Tom Bower, who is currently writing a biography on Meghan, claims the silence from the Sussexes' has been deafening.
Writing in Fabulous, Tom says the Duke and Duchess of Sussex have not sent any of the customary congratulations or messages of loyalty to their family in London.
Prince William is reported to have been supportive of the news.
Tom further claims that Harry has never liked Camilla and even blames her for his mum's marriage failing.
He writes: "Their insult was surely deliberate.
"It has been said by a number of people that Harry has always disliked Camilla and blamed her for wrecking his parents’ marriage.
"Perhaps the Sussexes’ deafening silence is Meghan’s way of declaring war.
"It is believed that she has never liked Camilla, and I am sure the feelings are reciprocated."
Tom goes on to say that Camilla may have been "suspicious" about Meghan.
He claims she may have found it "hard to believe" that Meghan would sacrifice her independence "to serve silently as a team player devoted to the monarchy".
His speculation comes as a royal insider has said Prince Harry and Meghan won't join Charles on the balcony of Buckingham Palace after his coronation.
A royal source told a newspaper that a "slimmed-down monarchy " will be on display when Charles finally ascends the throne.
They said it was possible that only Prince William, Kate and their children would join Charles and Camilla on the balcony when he becomes King.
The Queen was surrounded by her family and maids of honour when she waved to huge crowds below the palace after her coronation in 1953.
A source told the Mail On Sunday that Charles wants his coronation to be "far cheaper" than Her Majesty's ceremony, which cost £1.57million - the equivalent of £46million today.
