The first stage of this year's three-part Six Chair Challenge arrives, in which judges Simon, Rita, Nick, and Cheryl are given the opportunity to pick six acts to champion through to the later stages of the contest. The format has the potential to generate a great deal of drama in the studio, as the judges have the right to switch acts in and out of their line-up whenever they choose. Girl group 4th Power, 17-year-old singer Louisa Johnson, and youth worker Monica Michael are among the would-be stars who have already secured a place in this round of the contest, but it remains to be seen whether any of them will be able to win over the panel and progress further.
