ITV1's live final on Sunday night was seen by 12.9 million viewers, compared to 17.2 million last year and the smallest audience for the show's season finale since 2007 when the results show still went out on a Saturday night and 11.7 million saw Leon Jackson win. Some 15.5 million watched Joe McElderry's 2009 victory and 13.2 million saw Alexandra Burke win in 2008.
This year's final, in which Little Mix beat Marcus Collins to become the first group winners in the history of the competition, peaked at 15.3 million, having reached a peak of 19.4 million during the 2010 final.
The final included both finalists performing their version of the winner's song, a cover of Damien Rice's Cannonball, while there were guest appearances from Coldplay and Westlife. Former X Factor finalists Leona Lewis, JLS and One Direction plus Michael Buble performed on the Saturday night show when third-placed Amelia Lily was eliminated.
