Speaking about his latest book, ‘Elizabeth & Margaret The Intimate World of the Windsor Sisters’, the royal expert told ToDiForDaily that Meghan did not foresee how hard it is to be a royal.
Mr Morton said: “She just couldn’t hack it. She didn’t anticipate that it was difficult.
“It was like trying to climb Everest without ropes and without boots.
“It was like trying to climbs Everest in flip-flops.”
She added: “I didn’t fully understand what the job was: What does it mean to be a working royal? What do you do? What does that mean?”
Meghan said the “penny dropped” after she first met the Queen which was a “huge formality”.
She described how Harry had to show her how to curtsey just before meeting Her Majesty.
The Duchess explained how she had “confused the idea” of the Royal Family as regular celebrities.
She continued: “I grew up in LA, you see celebrities all the time. This is not the same but it’s very easy, especially as an American, to go, ‘These are famous people’. This is a completely different ball game.”
