Prince Harry and Meghan Markle’s big day was watched by a peak of 13.1 million, just after 1pm, on BBC1, making it the biggest peak figure so far in 2018.
The public broadcaster’s coverage, led by Kirsty Young, Huw Edwards and Dermot O’Leary, beat ITV, which peaked at 3.6 million around an hour later at 2pm.
The combined average audience, for BBC and ITV, was around 11 million.
The Duke and Duchess of Cambridge’s wedding in 2011 enjoyed a higher combined audience of 17.6 million, according to consolidated figures, but that number included people watching on catch-up.
