"The penchant for spouting word salad; the slightly awkward misplaced laughter; the courting of chat show hosts; the celebrity iPhone moments; the loathing of Donald Trump; the unfortunate bullying allegations.

"And then the penny dropped. Meghan! Kamala Harris reminds me of the Duchess of Sussex."

The commentator went on to say that Meghan was always said to have aspired to be the "first mixed race, female President of the United States" however, now Ms Harris could "beat her to it".

Secondly, she branded the US Vice President the new "darling of the US chat show scene", years after Meghan was "the toast of Oprah Winfrey".

She added that even though the duchess once "actively sought out a relationship" with Michelle and Barack Obama, now the couple are "busily endorsing Harris’s presidency".

Then, she wrote: "Both Meghan and Kamala spout this sort of pseudo-spiritual psychobabble that sounds perfectly progressive but doesn’t always make that much sense. The Duchess once declared: 'Reflecting on where I came from helps me to appreciate and balance what I have now.'

"But on reflection, might she have preferred to have come up with Harris’s now-infamous catchphrase: 'What can be, unburdened by what has been'.

"I mean, if you heard Meghan uttering these words at some point during the Sussexes’ 2019 tour of South Africa, you really wouldn’t have batted an eyelid, so accustomed had you become to her sociology-degree speaking style."

Ms Tominey also claimed that both women have spoken out in support of each other in the past.

She recalled Ms Harris's tweet shortly before the duchess's departure from the Royal Family: "Meghan, we are with you," with the former Suits actress welcoming Harris's nomination for vice president a year later.

The royal commentator concluded: "Meghan has not yet publicly endorsed Harris for president. But it can surely only be a matter of time."
