Emma Willis hosts the second of this year's Battle Rounds in the singing contest. Coaches will.i.am, Tom Jones, Olly Murs and Anne-Marie all return to their infamous red chairs as the acts they have chosen from the blind auditions go head to head and fight for their place on their coach's team. The singers that impress their coach the most remain in the competition with a chance of winning a recording contract. Will those that aren't so lucky be stolen by another coach or will they be going home?
