Meghan Markle and Prince Harry's request turned down by US over fears of upsetting King Charles

Biden then flew back to the States in the Air Force One.

It has now emerged that staff of the Duke and Duchess of Sussex reached out to the White House to ask if Meghan and Harry could fly back to the US in the presidential plane following the funeral.

However, the request was rejected due to fears it would "strain relations" between the US and Buckingham Palace.

A source told the Mail: "It would have caused such a commotion.

"It would have strained relations with the Palace and the new King."

Another insider added that the idea was a "non-starter".

Meghan and Harry stepped down as working members of the Royal Family in 2020.

The couple moved to California following a short spell in Canada and have lived there for the last three years.

Since departing the Royal Family, the Sussexes have launched multiple public attacks on the monarchy.

The Duke of Sussex released his autobiography in January 2023 and took part in several TV interviews, where he was critical of the Royal Family, to promote the book.

Prince Harry took swipes at Camilla, Princess Kate and his brother Prince William in his memoir titled Spare.

A source has now claimed that Meghan Markle regrets not taking a more active role in the book as the couple has been labelled "professional whinners" off the back of its release.

The source told Heat: "Meghan can now see that, whether it's fair or not, they are being viewed as these professional whiners and it's not as simple as her distancing herself, because she has to be seen as fully supportive of Harry.

"She's now regretting that she wasn't more hands-on or involved when he was putting his book together.

"This theory that she micromanaged what he wrote or had any say in the manuscript is totally wrong – it was Harry's book and she let him get on with it.

"The same went for his interviews and promo tours – that was evidenced by the fact she let him do those by himself and made a point not to interfere."
