The X Factor 2015: Revamped show returns this Saturday

The X Factor returns to ITV on Saturday night with new presenters, Olly Murs and Caroline Flack, and a revamped judging panel.

Out go Louis Walsh and former Spice Girl Mel B. They have been replaced by Radio 1 DJ Nick Grimshaw and singer Rita Ora.

Leah went to the show's London auditions to find out if the new signings are enough to get more people watching.
