He was crowned as the champion following an incredible duet with James Arthur.
Tonight’s tense final show saw Dalton, Anthony Russell and Scarlett Lee singing their hearts out with some of the show’s previous stars.
Anthony belted out I Predict A Riot with The Kaiser Chiefs, while Dalton sang The Power Of Love with James.
Following his winning performance, Ayda Field told Dalton: “I feel like I’m at your concert and everyone else is supporting you.
“I feel you are a future artist and you will change the world.”
Simon Cowell added: “I’ve heard some winner’s singles in my time, this was spectacular.”
After he was crowned the winner, Dalton broke down and struggled to speak.
Holding the microphone to him, Dalton whispered: “I've won The X Factor. I've just won.”
In the audience, his proud family were seen hugging each other and cheering.
