It's the third and final instalment of the Battles on 'The Voice UK'! Coaches will.i.am, Jennifer Hudson, Sir Tom Jones and Olly Murs return to the iconic red chairs as their acts battle head to head to keep a place on their coach's team. The singers that impress their coach the most will remain in the competition with a chance of winning a recording contract with Polydor Records; will those that aren't so lucky get stolen by the other coaches, or will they be sent home?
