Emma Willis hosts the live semi-final of the singing contest, as remaining contestants Tai, Lauren, Lucy, Donel, Ruti, Belle Voci, Jamie and Gayatri compete to win one of the four places in next week's grand finale. Only four acts can progress to the final and for the first time in the series, the decision of which acts will go through to the next round and which will be eliminated rests entirely with the votes of the viewing public. Members of Team Olly, Team JHud, Team Will and Team Tom look to move one step closer to winning a recording contract with Polydor Records. (thetvdb.com)
