As ever, Simon, Nick, Rita, and Cheryl are on hand to judge each contestant's skills with the mic, and presenters Caroline and Olly offer the singers much-needed moral support on-stage. Following today's show, the least successful contestants face another tense sing-off tomorrow, after which one unlucky act will be eliminated, leaving the finalists to progress through to the contest's last round next weekend.
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.
