X Factor has won the head-to-head viewing war with Strictly Come Dancing by more than three million viewers, new figures show.

The figures, confirmed by ITV, BBC and Sky, showed a peak audience of 12.8 million, a 50 per cent share of the TV audience, watched the squabbling between the judges on X Factor while Strictly peaked with 9.3 million, a 38 per cent share.

The hit ITV show, which was broadcast between 8pm and 10pm, averaged 11.3 million viewers, a 44 per cent share, with one million more viewers tuning in last night compared with the equivalent show last year.

But BBC One’s Strictly, which featured an unsteady performance by Amy Winehouse as a backing singer for her 13-year-old god-daughter Dionne Bromfield, drew an average of eight million, a 32 per cent share, between 7pm and 9.15pm.

While the two shows were head-to-head, The X Factor was watched by 10.9 million viewers, a 42 per cent share of the audience, while 7.7 million, a 29 per cent share, watched Strictly.

The controversial screening of the two shows simultaneously also led 1.3 million viewers to turn to their Sky+ and Sky+HD boxes, a spokesman for the broadcaster said.

Almost one million people chose to watch X Factor later, while around a third of that amount – 321,000 – set their Sky+ boxes for Strictly.
