Meghan Markle and her betrayal of the Royal Family: What she did to Queen Elizabeth II before she died is unforgivable

Meghan Markle has been told her actions before the death of Queen Elizabeth II were "unforgivable" and caused a bigger criss than Princess Diana's tragic death, according to a royal expert.

The former 'Suits' actress stepped down from her duty as a senior working royal along with her husband, Prince Harry, and moved to the United States to forge their own path in 2020.

But there have been several public spats between themselves and the Royal Family, owing much to their interviews criticizing the monarchs and the release of Harry's controversial memoir 'Spare'.

But Meghan's particular role in the dysfunctional family may have contributed to the demise of the Queen, who died at the age of 96 in September 2022, according to historian and biographer Hugo Vickers.

Vickers made the startling comments while appearing on The Sun's 'Royal Exclusive' show and called their feud the biggest crisis since Diana's death nearly 30 years ago.

"Well, 50 years doesn't take in the abdication, so I suppose the death of Diana in 1997 was the big crisis point," Vickers said.

"But, at the risk of being controversial, will the arrival of Meghan Markle prove to be a bigger one in the long run? Who knows."

Meghan's 'unforgivable' act

Meghan Markle has often pointed to her treatment from the UK media as a reason behind their family decision to leave for a new life in the U.S.

However, Vickers has cast doubt on that claim - and then went on to suggest Meghan's behavior exacerbated the Queen's condition.

"I think it's quite interesting all that because I was in Windsor the day they got married and the popularity and good will towards them was enormous," he added. "I don't think it was the press, she succeeded in evading that very, very quickly.

"What I find unforgivable, is the stress she put on the late Queen in the last couple of years of her life."
