The findings prompted questions about the arrangements enjoyed by the sisters, who have private careers outside the monarchy.
Nevertheless, the comparison with Harry is not necessarily a straightforward verdict on their standing. The Duke remains a globally recognised figure, with a public profile shaped by his military service, the Invictus Games and Megxit.
Beatrice and Eugenie, by contrast, maintain considerably lower public profiles. YouGov’s figures suggest their popularity is more difficult to assess, with substantial proportions of respondents unable to give an opinion on either Princess.
Harry’s return to Britain may offer an opportunity to reconnect with the country where he grew up, although the latest polling suggests that any improvement in his public standing remains far from assured.
The Duke has spoken openly about what bringing his family back to the UK means to him, particularly the opportunity for Prince Archie and Princess Lilibet to experience British schooling.
In an interview with British GQ published last week, Harry said: “Being able to put the kids in a British school has meant a lot to me. I didn’t know how important it was to me.”
