The comment came as the Duchess of Sussex said in an interview with The Cut magazine that “just by existing” she and Harry were “upsetting the dynamic of the hierarchy” before they stepped down as senior working royals. Journalist Allison P. Davis asked Meghan if there was room for forgiveness between her, the royals and her own family, to which the Duchess replied: “I think forgiveness is really important. It takes a lot more energy to not forgive. But it takes a lot of effort to forgive. I’ve really made an active effort.”
Dr Shola told her 156,000 Twitter followers: “The best thing to happen to the Royal Family in 100 years was Princess Diana followed by Duchess Meghan Markle.
“They rejected both women – real assets in a modern progressive world.
“For a monarchy whose singular purpose is to ‘survive’ they’re walking themselves into extinction.”
The interview with Meghan has sparked a frenzied debate over the meaning of some of her remarks.
“Because they are not working members of the Royal Family, there is no reaction from any of the Palaces but I suspect there would be a sense of rather weary resignation as they read these comments and try to understand them.
“In some instances, they are somewhat ambiguous.”
He continued: “Opinion will be divided as to whether you’re a supporter and sympathetic to Meghan or not.
“Those who are her supporters and there are many of them, mostly younger people, will feel that these are entirely legitimate views and that it is interesting to hear from her… Those who are less sympathetic to her may feel that a period of prolonged dignified silence would be more helpful.”
Dr Shola’s comments were made ahead of the 25th anniversary of Princess Diana’s death in Paris.
The princess was 36 when the limousine carrying her and her lover Dodi al-Fayed crashed into a tunnel below a bridge as it sped away from photographers chasing it on motorbikes.
Her death plunged the monarchy into crisis, coming after the disintegration of her marriage to Prince Charles with its revelations of feuding, adultery and the misery she felt in her role as a royal.
The flag at the Princess of Wales’s family home has been lowered to half mast to mark the anniversary of her death.
Diana’s brother Earl Spencer shared a poignant photograph of the tribute at Althorp in Northamptonshire.
The princess is buried on an island in the middle of an ornamental lake, known as The Oval, on the Althorp estate.
