The Voice UK is to be significantly re-tuned in a bid to prevent the ratings slump that affected the first series.

BBC1 has worked with producers Talpa Media and Wall to Wall Television to introduce the format changes, which will see the singing contest broken down into four main stages when it returns in the spring.

The familiar blind auditions and battle rounds will remain in place, but the live stages will be scaled back to introduce a “knockout” round. At this point, the contestants will be able to choose a song to perform in order to secure their progression to the live rounds.

The coaches will also be given the chance to “steal” one of their rivals’ rejected singers following the battle rounds.

Other changes will give the coaches - will.i.am, Jessie J, Tom Jones and Danny O’Donoghue - the chance to select more contestants during the blind auditions, while each live round will feature all of the contestants.

“We can’t wait for The Voice UK to return to Saturday nights,” said Moira Ross, The Voice UK’s executive producer for Wall to Wall. She added that it will be an “extraordinary series”.

The Voice’s blind auditions peaked with 11.99m (47.02%) viewers last year, but this tailed off dramatically for the later rounds, which slumped to a low 5.13m (27.51%) for the penultimate episode.
