The successful acts that have made it through the auditions return for boot camp stage of the competition at London's Wembley Arena. In small groups the acts perform live on stage and are learn straight away as to whether they're through to the six seat challenge. Just 57 of them make it through to the next phase. The judges are given the categories they will be mentoring. Cheryl has the her girls and the six seat challenge gets underway. Lola Saunders, Chloe Jasmine, Shanay Holmes, Orla Keogh, Stephanie Nala, Monica Michael, Kayleigh Manners, Ten Senah, Emily Middlemas, Chloe O'Gorman, Lauren Platt and Kerriane Covell all attempt to impress.
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.
