The wedding of Prince William and Catherine Middleton attracted a peak viewership of 20 million on the BBC, at the end of the ceremony in Westminster Abbey, according to the broadcaster.
The disappointing turnout comes after more than one-third of Britons (36 percent) say their opinion of the family has become more negative than it was 10 years ago.
Just 21 percent say their views on the Royal Family have gotten more positive over the past decade, with another 41 percent saying their overall opinion has stayed the same, the survey by polling company Savanta found.
And three in 10 say they have become less interested in news about the family over that time, while 22 percent say they have grown more interested.
Savanta interviewed 2,093 UK adults aged 18+ online between 24th and 26th March 2023. Data were weighted to be representative of the UK by age, sex, region, and social grade.
