Photos: The Queen retains her spot as Britain's most popular Royal

Prince Harry and Meghan Markle's popularity ratings have fallen to their lowest levels ever after their bombshell interview with Oprah Winfrey, according to a new poll.

The couple's popularity has plummeted in the wake of the explosive broadcast, in which the couple made accusations of racism within the Royal Family. But the British public appear to have reacted negatively to the couple's interview, with Prince Harry's popularity plunging 15 points since the broadcast, according to a new YouGov survey. 

Meghan's popularity has also sunk by 13 points in the last 10 days, figures from the poll show. Meanwhile, in a sign of unwavering show of support, Britons continue to be most fond of the Queen, with four in five people (80 per cent) liking her, the survey says. 

Prince William and his wife Kate also remain very popular, according to the poll, with about three quarters of Britons giving them favourable reviews. 

Prince Andrew remains by far the most unpopular royal, with an 82 per cent negative view, according to the poll.
