Meghan Markle and Prince Harry's popularity has declined in both the UK and the US.

Kate Middleton and Prince William have seen their popularity rise.

A report by Daily Express UK highlighted the contrast in popularity trends.

William and Kate's composed response to Harry and Meghan's allegations has helped their ratings.

A YouGov survey in September showed Prince William with a 74% approval rating.

Kate Middleton is viewed favorably by over 62% of respondents.

In the US, a Redfield & Wilton survey placed Kate as the most loved royal.

Kate's net approval rating is +35, while William's is +24, and Harry's is +22.

The royal popularity dynamics are shifting in favor of William and Kate.
