The Queen will have found Prince Harry and Meghan Markle's behaviour "deplorable" amid new claims about the Royal Family, an expert believes.
Royal commentator Richard Fitzwilliams thinks the latest allegations made by the Duke and Duchess of Sussex will have a profound impact on the Firm.
In March, Harry and Meghan opened up about their struggles as working royals in their bombshell interview with Oprah Winfrey.
More recently, Harry opened up about his mental health and childhood - in particular the pain he felt after the death of his mum Diana, Princess of Wales - in a new series with Oprah, The Me You Can't See.
Speaking to the Daily Star, Mr Fitzwilliams said: “The Sussexes’ activities, when they’ve spoken out, have been very very damaging. There’s no doubt about it.”

During his chat with Oprah, Harry also claimed that his family told him to "play the game" when he admitted his struggles with royal life.
Asked if Her Majesty would have taken Harry’s comments personally, Mr Fitzwilliams responded: “She has realised how unhappy they were, but speaking out in the way they have is a totally different thing.”
The couple have so far avoided directly criticising the Queen.
Recent reports suggested that Charles would “close ranks” if Harry did so.


Mr Fitzwilliams continued: “The Queen will have found the way the Sussexes have handled things, I think, deplorable.”
It comes as sources say Meghan Markle is "fearful" of losing her title as The Duchess of Sussex.
According to an insider, Meghan thinks that losing the title she was bestowed after marrying Prince Harry in 2018 could be a "PR disaster".
A source close to the former Suits actress said: "She's told Harry that they need to tone down the attacks on the royal family - she's afraid they'll take away their royal titles, which would be a PR disaster.
"Right now, she's inundated with offers, and that's in part to being a Duchess."

An insider has also claimed that Prince Harry's desire to attend the Queen's Platinum Jubilee celebrations next year would be a " fresh headache " for the Royal Family.
The Jubilee celebrations, announced today, will see a four-day Bank Boliday from Thursday, June 2 to Sunday, June 5, 2022, and feature events at Buckingham Palace to mark the Queen's 70 years on the throne.
The insider told The Sun : “Harry wants to be there. It is already causing a headache and is going to be very awkward.
“Where will they be positioned if they turn up? What events can they attend? Will we put them on the Buckingham Palace balcony for the flypast?"
They added: “This is a celebration for the Queen’s 70 years of service to the nation and should not be overshadowed."
