The X Factor is a British television music competition to find new singing talent. The ninth series began airing on ITV on 18 August 2012 and ended on 9 December 2012. Dermot O'Leary returned as presenter of the main show on ITV, whilst Caroline Flack and Olly Murs returned to co-present The Xtra Factor on ITV2. Louis Walsh, Gary Barlow and Tulisa returned as judges. Nicole Scherzinger was confirmed as the fourth permanent judge after Geri Halliwell, Leona Lewis, Rita Ora, Mel B, Anastacia and Scherzinger herself stood in as guest judges for the vacant position left by Kelly Rowland. After the show of 8 December, two of Scherzinger's acts, James Arthur and Jahméne Douglas, became the top two, meaning that Scherzinger was guaranteed to win. Arthur was announced as the winner on 9 December, and released a cover of Shontelle's "Impossible" as his winner's song. As of 2016, it is the most successful winner's single in the show's history.
