District3 have become the sixth act to be eliminated from the live phase of this year's X Factor, losing the Sunday sing-off against fellow boy band Union J.
Gary Barlow and Nicole Scherzinger both thought Union J should stay, which, with groups mentor Louis Walsh abstaining, meant District3 were out.
On Saturday night, District3 sat on stools, one of them a piano stool, to sing Tears in Heaven. Union J performed an emotional version of Fix You, dedicating it to loved ones in the armed forces.
In the Sunday sing-off, District3 sang Just The Way You Are by Bruno Mars, performing competently despite looking shaky. Union J responded with Adele's Set Fire To The Rain, in what seemed clearly to be a more confident performance.
Opening the judging, Louis Walsh - the mentor to both endangered acts - refused to choose between them. That eliminated the possibility of deadlock. Gary Barlow went next, saying that he'd previously much favoured District3 but that the sing-off was "one of your worst vocal performances to date". Telling Union J "I felt you wanted it that bit more", he voted to send District3 home.
Nicole Scherzinger complimented both groups but also favoured the "more mature" Union J. District3 were already out without Tulisa Contostavlos having to vote. She said she would have voted to save District3.
A poll of RadioTimes.com readers overwhelmingly named Christopher Maloney as the act who most deserved to go based on Saturday night's performances. The Liverpudlian garnered a huge 42% of the total vote. Rylan Clark, who has topped the vote in every single previous week, was the second most disdained contestant on 37%. District3 were least popular with 12% of voters, with Union J a long way behind on 2%.
Ella Henderson, Jahmene Douglas, James Arthur, Christopher Maloney, Rylan Clark and Union J survive to sing again next week.
