Caroline and Olly present the results of last night's live show, revealing which acts are safely through to the next round. The two lowest scoring scoring contestants compete in a sing-off in front of judges Nick, Rita, Cheryl, and Simon, to decide who gets to stay in the competition and who gets eliminated. With performances by One Direction and Jess Glynne.
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.
