The ITV programme is presented by Maya Jama with a judging panel consisting of Gary Barlow, Craig David, Dawn French and Alesha Dixon.
Simon Cowell was originally set to be the head judge on the panel, but was replaced by Barlow.
However, instead of going straight into the final, the winner of an episode has to decide whether to come back the next night to perform again with the risk of being dropped from the competition at that point.
[10][11] The winner of the fourth, fifth and final episode was London-based singer Nadiah Adu-Gyamfi, who has featured under the stage-name "Moko" on two singles by electronic music duo, Chase & Status[12] including on the UK Top 5 hit single "Count On Me".
[13] Nadiah "Walked the Line" one final time in the last episode and won the audience vote, taking home the £500,000 jackpot.
