Leona Lewis has been named the best-selling X Factor act in the UK.
The latest sales figures show that the singing contest has produced sales of 30 million singles and 18 million albums in the UK since it started back in 2004.
Lewis leads both of the bestsellers lists, having sold 3.9m albums in the UK since her win in 2006 and around 4.4m singles.
Olly Murs is in second place on the singles tally with 3.9m songs sold, while JLS are third having shifted 3.4m tracks during their career so far.
However, those positions are reversed on the albums list, with JLS in second place with 2.7m records sold and Murs in third with sales of 2.6m.
Alexandra Burke holds on to the title of the best-selling X Factor single with 'Hallelujah', but James Arthur's 'Impossible' is only 30,000 sales behind having shifted 1.2m copies since December 2012.
