Meghan should have drawn cues from Wallis Simpson, according to royal author Anna Pasternak, who has written extensively about the American.

Mrs Simpson, the American divorcee who fell in love with the Duke of Windsor, is reported to have offered a “tactful and “self-deprecating” interview.

The tell-all interview was provided by the exiled Duke and Duchess of Windsor in March 1970, more than 30 years after the royal’s disastrous abdication.

Ms. Pasternak wrote in a Daily Telegraph column that the 1970 interview with BBC journalist Kenneth Harris “seemed equally electrifying and scurrilous at the time, making headlines on both sides of the Atlantic.”

While the author drew similarities between the two women’s tales, the commentator pointed out that Meghan and Wallis’ approaches and situations were dramatically distinct.

For instance, she points out that the Duke and Duchess of Windsor were banished to France, while Meghan and Harry decided to abandon the Royal Family and migrate to the United States.

Second, Ms Pasternak reported that in her interview, Wallis appeared eager to “build bridges,” while Meghan “appears to want to up the ante against her in-laws.”

MORE ON HER VIEWS

You would have thought that Wallis might take the chance to settle scores against her frosty in-laws when the Windors talked to Kenneth Harris from the silvery grey drawing room of their Parisian house, considering the plethora of falsehoods that the Royal family had levied against the Duchess for the previous 34 years.

Or that the Duke would eventually be able to vent his long-held grudges against his kin.

The Windsors were unstintgly generous in their replies and did not attack the Royal Family once.

There was no hint of resentment but a sanguine recognition of what must have seemed her own unsurvivable moments, when, during the abdication crisis, she became the world’s most despised woman.

Watching this poignant interview now, through the lens of the Sussexes’ explosive bid, which even Oprah calls ‘shocking,’ the Windsors does not seem sweeter, nor their stance more quaint.

The saddest part is that, through their exile, Wallis and Edward remained dutiful and patriotic to the end.
