The former This Morning host and her dance partner Artem Chigvintsev left the competition after finishing in the bottom two alongside Girls Aloud star Kimberley Walsh and professional Pasha Kovalev.
Both couples performed their routines for a second time in the dance-off, with Britton dancing a salsa to 'You'll Be Mine (Party Time)' and Walsh a Viennese waltz to Christina Perri's 'A Thousand Years'.
Craig Revel Horwood gave his verdict first, and chose to send Britton home. "It's a no brainer - Kimberley and Pasha," he said.
"The cleanest performance for me was Kimberley and Pasha," said Darcey Bussell, making it two votes to Walsh.
Bruno Tonioli made it a unanimous decision by choosing to save the Girls Aloud star. "Well, with all due respect, I thought one couple was outstanding and that couple is Kimberley and Pasha," he said.
Britton's exit means she will not get to take part in Strictly Come Dancing's Children in Need special, which is to be held at Wembley Arena next Saturday (November 17).
"This is the best party on the television, it's the best programme in the world, and I'm thrilled to have been part of it," she said upon hearing the judges' verdict.
"Everyone else - good luck, good luck, good luck! It's the best party. You've got dancing in the drawing room, you've got snogging upstairs, you've got throwing-up in the garden. It's been fantastic. You really do live that - the throwing-up mostly!
"Artem, I've loved it," she added, turning to her dance partner. "I wouldn't have swapped you for anything. There have been highs and lows, we've got to know each other pretty well, and I do adore you… and Kimberley and Pasha are fantastic."
Chigvintsev added: "It has been very lovely."
Sunday's results show featured Dutch classical musician Andre Rieu, who performed 'The Rose'.
Strictly Come Dancing continues live from Wembley Arena next Saturday (November 17) at 6.30pm on BBC One.
