It's the first of the knockout shows as the remaining 12 acts sing for a place in the semi-finals. Coaches Will.i.am, Tom Jones, Olly Murs and reigning champion Jennifer Hudson can pick only one act from their teams to progress in the competition, so there are some tough decisions to make. Helping them are R'n'B star Craig David, members of the Black Eyed Peas, Australian pop queen Kylie Minogue, 2006 winner of The X Factor Leona Lewis and The Voice UK's reigning champion, Mo Jamil. Presented by Emma Willis.
