One of the most exciting elements of the show will always be the big Sunday night eliminations, especially if the dreaded Deadlock comes into play.

1. Laura White (series 5)
Wigan lass Laura was tipped for X Factor success in 2008's early stages, but found herself in a tough girls group with the public's favourite indie fairy Diana Vickers and future victor Alexandra Burke. Even so, no-one expected her to leave as early as the fifth week, especially with Ricky Gervais lookalike Daniel Evans still knocking around.
