The boot camp stage of the competition continues at London's Wembley Arena. Sharon continues wiith the over 25's and next to perform is Shelley Smith who really manages to impress. Katie Markham, Andrea Magee, Lorna Simpson and Zoe Devlin also impress leaving Sharon with some tough decisions to make. Gary Barlow takes a tough stance as he has to select six groups. Brick City and Rough Copy are up first both hoping to impress. Some of the groups fail to impress though when they are told they sound dated. Kingsland and Xyra manage to impress but Tenors of Rock manage to split the panel. Code 4 perform are next before a newly formed girl band perform together for the first time. Next of Kin are the last of the groups to perform, and with all his seats full, Gary needs to decide whether to ditch them or one of the acts already through to judges' houses. Last up are the boys who are being mentored by Louis. Sam Callahan is the first to perform but Louis has some serious doubts whether he can win the competition for him. Barclay Beales manages to shock the judges with his performance before Paul Akister takes to the stage. Alejandro Fernandez, Ryan Mathie, Luke Friend and Giles Potter also hope to impress but nerves get the better of some of them. Tom Mann manages to get the audience on his side and hopes to impress Louis as well. Nicholas McDonald is the last perform to perform also hoping to gain a place in the next phase of the competition.
Each X Factor judge is in charge of a different section of singers on the show. The judges do not know what section of the competition they will be in charge of until the audition process has finished. Each judge then has to pick four acts to take forward to the live section of the show. Each week the two acts with the lowest amount of public votes have to sing again in a final showdown after which the judges decide who should be eliminated. Once there are only five acts left remaining it becomes left to the public to decide who should go.
