The Voice UK - Season 4 (2015)

The blind auditions continue as superstar coaches will.i.am, Sir Tom Jones, Rita Ora and Ricky Wilson compete to ensure they secure the best voices on their teams. There are many surprises behind the red chairs including trumpet-playing Dawn 'with the horn' Allen, Welshman Cai Williams and Tim Arnold, aka the Soho Hobo. The judges also hear from Liverpool duo The Mac Bros.

Tonight we hear from celebrity chauffeur booker Vikesh Champaneri, 19-year-old Essex rapper Brooklyn and former lead singer from 80s boyband Brother Beyond, Nathan Moore.

The competition is now fiercer than ever as places on each team become increasingly limited. The judges hear from Beckenham duo the Rise, spoken-word poet Lara Lee and Damian Dalton Smith - older brother of actress Sheridan Smith.

This is the last chance for artists to claim the remaining places on the coaches' teams. In this final round we hear from Warrington Disney princess Sarah Dunn, singing waiter Mitch Miller and Tina Turner impersonator Andrew Marc.

As the battles commence, the premise is simple: one song - two voices - one winner. Each battle sees two artists from the same team compete against each other in a vocal showdown. After each battle, the artists' own coach must decide who will progress to the knockout stage - and who will be sent home. But it's not quite over for the losing artist. The other coaches can steal a losing artist for their own team. Each coach gets two steals - if they missed out on an act during the blind auditions, this is their chance to finally grab them.

In a nail-biting final battle, the remaining artists of each team take to the stage to secure their places in the next round. Will they be able to convince the coaches that they have what it takes to be this year's winner of The Voice UK? Superstar coaches will.i.am, Sir Tom Jones, Rita Ora and Ricky Wilson will each take eight artists through to the Knockouts stage.

Emma Willis and Marvin Humes present the first of the knockout rounds. The coaches watch each of their eight contestants perform and must choose the best three acts from their team to continue on to the live shows. Rita and will.i.am pit their remaining artists against each other to compete in one last round before the live shows. It is now the artists who take control - they must each choose one 'killer song' that they think will give them the best chance to impress their coach. Which of Rita's acts, including Welsh school teacher Joe Woolford, Liss Jones or duo ...

It's now up to Ricky Wilson and Sir Tom Jones to pit their remaining artists against each other in one last contest before the live shows. Sir Tom Jones must choose between acts including bricklayer Sasha Simone, gospel-singing duo Joyful Soundz and spoken-word poet Lara Lee. Over on Ricky Wilson's team, will Scottish fireman Stevie McRorie, schoolgirl Claudia Rose, or powerhouse Hannah Symons have what it takes to make it through to the next round?

For the first time this series Rita Ora, will.i.am, Ricky Wilson and Sir Tom Jones bring their teams to perform live in front of the nation in a bid to secure their place in the semi-finals. In the first live show of the series, the viewers at home get their first chance to vote on who remains in the competition and who goes home. Plus live performances from Olly Murs and 2014's winner Jermain Jackman, performing his debut single How Will I Know.

Emma Willis and Marvin Humes reveal the results of the public vote and announce who has gained a coveted place in the semi-finals.

The semi-final sees the coaches' remaining eight acts perform live in front of the nation. Each act performs one solo song and one song with their coach and remaining team. They then face the public vote. The acts gaining the highest number of votes will go through to the final.

The contestants have made it through the blind auditions, battles and knockouts - now only four remain. In the grand final, the power lies with the viewers as the final four artists face the public vote in a bid to be crowned winner of The Voice UK 2015. Each artist performs one solo song, and Sir Tom Jones, Ricky Wilson, Rita Ora and will.i.am perform one song with their remaining artists. The viewers will also be treated to a special performance from Paloma Faith and the Script.
