Viewing figures for the second auditions show of The The X Factor 2012 enjoyed a slight rise to 8.9m – following last weekend’s disappointing ratings for the launch edition.

Saturday’s programme attracted an average of 8.4m on ITV1 with a further 475,000 watching the show on the catch-up service ITV+1 an hour later.

Overnight figures also suggested that the audience peaked at 10.9m – over 1m more than the peak audience for the first show of the series.

Last weekend’s audience was the lowest for an opening edition of The X Factor since the 2006 series – and 2m fewer than tuned in to watch Tulisa, Gary Barlow and Kelly Rowland make their debut in 2011.

Show producers blamed the heatwave on the fall in viewers, with a spokeswoman saying, “The X Factor was launched on the hottest day of the year and its audience was still double that of the nearest programme.”

Saturday night’s show saw chimney sweep Kye Sones, acoustic performer James Arthur and witty songwriter Lucy Spraggan establish themselves as potential contenders in audition footage from London, Manchester and Newcastle.

Lucy in particular has already reaped the benefits of an appearance on the show after her ‘beer fear’ anthem Last Night soared to the top of the iTunes singer/songwriter charts as well as reaching the top five in the iTunes song chart.

Her album Top Room At The Zoo, which was released on an independent label last year, has also reached the top ten of the iTunes album chart.
