Holly Willoughby and Reggie Yates present the first live round of the singing contest, in which the 12 remaining acts - Ash, Matt, Sarah, Andrea, Karl, Mitchel, Alys, Joseph, Mike, Cleo, Leah and Leanne - perform for a place in next week's semi-final. After all three acts in each team have performed, Jessie J, Tom Jones, Will.i.am and Danny O'Donoghue will choose one to progress straight through to the next round - leaving the remaining two on each team going head to head in a public vote. The results can be seen at 9.30pm.
Hosted by Emma Willis and Marvin Humes, the show features four musician coaches: will.i.am, Boy George, Paloma Faith and Ricky Wilson, who will coach only the most talented vocalists. The show's innovative format features three stages of competition: the first begins with the blind audition, then the competition enters into a battle phase, and finally, the live performance. The show's casting team is working with the music industry and searching the country for the best singers to bring to the blind audition process.
During the blind auditions, the decisions from the coaches are based solely on voice and not on looks. The coaches hear the contestants perform, but they don't get to see them - thanks to rotating chairs.
