The Gavin and Stacey finale attracted an average of 12.3 million TV viewers – the largest Christmas Day audience in more than a decade, overnight data shows.
The new Wallace and Gromit film also attracted a large audience, with more than 9 million viewers tuning in to watch the latest instalment.
Nearly 7 million people watched the King’s Christmas message on the BBC and ITV.
All figures are based on “overnight” TV ratings – which do not include viewers who watch Christmas specials on catch-up services during the rest of the festive period.
The finale of Gavin and Stacey was the most watched show on Christmas Day since the previous Wallace and Gromit film in 2008.
An average of 14.3 million viewers tuned in to watch the animated duo that year in A Matter Of Loaf And Death.
