Prince Harry's popularity in Britain has dropped to its lowest level in two years after he attacked his father King Charles III in his latest television interview.

Only 27 per cent of UK adults now have a positive opinion of the Duke of Sussex and 63 per cent have a negative view, which is his worst score since early 2023.

Younger people feel more favourably towards Harry, with 18 to 24-year-olds having a net favourability rating of 0, while it is -67 for those aged 65 or over.

The YouGov poll also found the popularity of Harry's wife Meghan Markle has hit a record low with just 20 per cent now having a positive view and 65 per cent negative.

The negative view of Meghan has remained unchanged since the previous YouGov survey in February - but the positive view has slipped from 21 per cent.
