Prince Harry and Meghan Markle's lengthy statement published on their website has been found to contain a subtle dig at Princesses Beatrice and Eugenie.
The 1114-word statement came just hours after the couple revealed they would cease to use the word "royal" and will keep their HRH titles but won't "actively use" them.
A royal source has claimed that a section of their statement - complaining that the Royal family is treating them differently to other family members - is an attack on Harry's cousins.

The part of the statement that has raised eyebrows reads: "While there is precedent for other titled members of the Royal Family to seek employment outside of the institution, for The Duke and Duchess of Sussex, a 12-month review period has been put in place.
"Per the agreement The Duke and Duchess of Sussex understand that they are required to step back from Royal duties and not undertake representative duties on behalf of Her Majesty The Queen."
According to The Mirror, the royal source believes this is a clear reference to Beatrice and Eugenie.
"It's pretty clear they are referencing minor royals such as Princess Beatrice and Princess Eugenie, which is an odd association to make for two people whose associates were once claiming they had single-handedly modernised the monarchy."
The princesses are not considered senior working royals, as Harry and Meghan were, because they aren't carrying out full time duties for Her Majesty.
The daughters of Prince Andrew and Fergie are ninth and 10th in line to the throne and both have full time jobs they have sought independently.
Princess Beatrice has worked at private wealth firms and as a Sony business development associate until 2014, reports the Daily Mail.
And Eugenie worked at art gallery Hauser & Wirth in London's Mayfair.
The sisters both attended university, Beatrice studied History and the History of Ideas at Goldsmith's University and Eugenie graduated from Newcastle University after studying English Literature and the History of Art.
