Princess Diana's designer believes Meghan Markle is trying to damage the royal family.

Ever since she joined the royal family, Meghan has been viewed as the villain of the story. She was also subject to media scrutiny because of her past life as a divorcee and former actress.

Unfortunately, even Princess Diana's designer thought the Duchess of Sussex ruined the royal family, especially Prince William and Prince Harry.

One of the designers of Princess Diana's iconic dresses, David Emanuel, told GB News host Dan Wooton on TLC's "Say Yes To The Dress U.K" that the late princess would be deeply shocked by how Prince William and Prince Harry ended up feuding.

"I think if she was alive it wouldn't have happened with the two brothers. She wouldn't have allowed it. She'd have smoothed the waters," the designer said.

Wooton is also a vocal critic of Meghan and Prince Harry. He asked the designer what Princess Diana would think once she sees his son's choice of wife.

Emanuel responded, saying that Prince Harry's wife (who he referred to as "the American woman") shockingly - and ultimately - messed up the royal family after messing up her own family.

It was not the first time he spoke ill about Meghan.

In July, Emanuel was asked about the Duchess of Sussex. But he told the Daily Mail columnist that he could not utter the name of the American woman. He then criticized his outfit during Queen Elizabeth II's Platinum Jubilee celebration, saying that she looked like in a nurse's uniform while channeling her inner Wally Simpson.

He talked about Wallis Simpson, another American divorcee who caused the downfall of exiled royal, Edward VIII. He was supposed to rule the monarchy, but he gave up his royal life and abdicated to move to France and spend the rest of his life with Simpson.

Former Tory MP David Mellor said that Meghan thought she would become Princess Diana after marrying Prince Harry. However, she eventually had no willingness to do the works the late princess did.

Princess Diana's biographer Tina Brown also shared a similar statement as Emanuel, saying that Princess Diana would be anxious about the direction Prince Harry took.
