Dermot returns with the results of this week's viewer vote. Susan Boyle and Mariah Carey perform live on stage. John and Edward and Olly learn that they are in the bottom two this week and have to perform again in the final showdown. The judges then decide to save Oliver leaving John and Edward eliminated from 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.
