Baby Archie is just a few weeks old, but his birth has given brand Sussex a big boost, especially for his mother. A royal historian noted that the current Meghan Markle is “in a more powerful position” since she married Prince Harry and joined the royal family.

Royal historian Anna Whitelock said that the arrival of Archie Harrison Mountbatten-Windsor has made Meghan Markle a “more powerful” member of the royal family. In addition, the duchess has a considerable influence on Prince Harry, who loves her very deeply. “She is married to Harry, he clearly dotes on her and adores her, she clearly has a great deal of influence over him,” Whitelock said on Yahoo's The Royal Box.

In terms of popularity, a recent YouGov survey suggests that Meghan is catching up. While she is a relatively new member to the royal family, the Duchess of Sussex is now ranked the sixth most popular royal.

On the same survey, Queen Elizabeth II led the result with a positive opinion of 72 percent, followed by Prince Harry with his 71-percent rating. In last year’s YouGov survey, it was Prince Harry who was ranked first, followed by his grandmother.

The second in line to the throne, Prince William, got a rating of 69 percent and ranked third in the latest survey. His wife, Catherine, Duchess of Cambridge, is at fourth place, while his grandfather, Prince Philip, was ranked fifth.

While it was a big move for Meghan to basically ditch her thriving Hollywood career and move to England when she married Prince Harry, she quickly learned the ropes and was able to establish her own fanbase in such a short period of time. Obviously her prior fame as an actress helped, but she is also gaining praise and approval for her advocacy efforts.

According to Whitelock, the royal family should take “due hold” of her growing popularity. “She’s now the media darling royal and she has a baby as well. She holds all the cards now,” the historian added. “Meghan is incredibly powerful and the Royal Family know that or if they don’t know that, they should take due hold of that.”
