When asked, 82% of respondents said King Charles should encourage his brother to give evidence to police in the US, while only 6% thought he should not encourage him.

With a slew of negative headlines around Andrew and Epstein's relationship, two royal households have taken the unusual step of issuing statements. Both Buckingham and Kensington Palace laid out their response within a couple of hours of each other, following fresh allegations.
Last year, the King stripped his brother of his titles, honours and his home. But it's not just Andrew's reputation and judgement on the line.
The revelations could threaten the future of the monarchy if the public feels the Palace response doesn't reflect the scale and significance of this scandal.
