Prince Harry and Meghan Markle’s bombshell Oprah interview sparked something which is "changing" Britain and "could topple the archaic monarchy," a royal expert has claimed.

The Duke and Duchess of Sussex made headlines for their remarks about the Royal Family during an interview with U.S. chat show host Oprah Winfrey.

Meghan accused the Firm of racism, claiming a member of the family questioned what the colour of Archie’s skin would be prior to his birth.

She also alleged she was denied mental health support, while Prince Harry claimed Prince Charles and Prince William are "trapped" within the Firm, adding that his father removed security from the young couple when they were in Canada.

The remarks were discussed worldwide with many calling for an overhaul of the monarchy, an institution that is centuries old.

Anna Pasternak, author of Princess in Love and The Real Wallis Simpson: A New History of the American Divorcee Who Became the Duchess of Windsor, told Vanity Fair she believes the monarchy "may way topple" following Prince Harry and Meghan Markle's interview.

Ms Pasternak claims the couple’s reveal |sparked something so fundamentally incendiary| that it is "changing the face of Britain."

She added that she is "not 100% sure" Prince Charles will ever ascend the throne, and the Royal Family could see an overhaul very soon.

The expert went on to suggest that Prince William may takeover from the Prince of Wales instead as "he's younger, more relatable."

The Royal Family’s future has come into question following the death of the Queen’s consort, Prince Philip, the Duke of Edinburgh.

Prince Philip died at the age of 99 "peacefully" at home with his wife, Queen Elizabeth II, at his side.

The Duke had been hospitalised in early March 2021 and underwent a heart operation and treatment for an infection, which was said to have gone well.

During that time, Meghan and Harry’s Oprah interview aired and CBS came under fire for not postponing the show.
