It's the first of the knockout shows on The Voice UK, as 12 acts sing for a place in the Semi Finals. Coaches Jennifer Hudson, will.i.am, Sir Tom Jones and Olly Murs can pick only one act from their teams to progress in the competition, so there are some tough decisions to make. Helping the coaches make those decisions are very special guests Craig David, members of The Black Eyed Peas, Kylie Minogue, Leona Lewis and The Voice UK's reigning champion, Mo Jamil. Those who make it through will be one step closer to the chance of winning a recording contract with Polydor Records.
