KEY POINTS

  • Prince Harry and Camilla Parker Bowles have equal scores in YouGov's latest "Royal Favorability" tracking
  • Meghan Markle received a negative favorability score in the poll
  • The Duke and Duchess of Sussex remain popular among adults aged 18 to 24

Meghan Markle and Prince Harry may have experienced a drastic drop in popularity in the United Kingdom after stepping down as senior members of the royal family earlier this year, a new poll suggests.

Months after resigning from their royal posts, the Duke and Duchess of Sussex have scored lower in terms of favorability among adult U.K. residents in the latest numbers from market research firm YouGov's "Royal Favourability Tracker."

Released Thursday, the results of the poll revealed that 48% of adult respondents have a positive impression of Prince Harry, while 47% view him negatively, which gives him a net score of 1. His latest favorability score is 19 points lower compared to his numbers in March, the firm said.

His wife, meanwhile, had an 18-point drop in favorability among adults in the U.K., according to the poll results. Markle received a thumbs up from 33% of respondents but nearly 59% had a negative opinion of the duchess, giving her a net favorability score of -26.

Markle's score is the "second lowest" among the entire royal family, the firm said.

However, the Duke and Duchess of Sussex remain popular among adults aged 18 to 24 in the U.K., carrying net scores of 28 and 20, respectively.

Camilla Parker Bowles split public opinion, with 44% of adults saying they had a positive impression of Prince Charles' wife and 43% having the opposite opinion. This leaves the duchess a net score of 1, which means that, based on the poll, she now has a higher favorability score in the U.K. than Markle.

"Camilla Duchess of Cornwall, the woman publicly dubbed by Diana, Princess of Wales as 'the rottweiler' and who was the most hated woman in Britain for decades, is now more popular than Meghan," Daniel Elser, a royal correspondent for News.com.au, noted.

While the Sussexes suffered a blow in their favorability rating, Prince William and Kate Middleton's popularity among the public has remained "steady," the firm said.

Prince William's net score also dropped in the latest round of YouGov Royal Favourability tracking, but it wasn't as significant as Prince Harry's. About 80% of adult respondents have a positive opinion of the Duke of Cambridge, while only 15% view him negatively, giving him a net score of 65. This is four points lower than the 69 he scored in March.

Meanwhile, Middleton is one of the few royals who have seen an increase in their favorability score. The Duchess of Cambridge received 76% positive reviews and 14% negative from adults, resulting in a net score of 62. This is five points higher than her favorability score of 57 in March.

Queen Elizabeth II's net score also increased by two, from 69 in March to 71 in the latest poll. Her Majesty received an 83% favorable response and only 12% negative, giving her a net score of 71.
