The six-part series will see contestants try to win a prize of £100,000 by answering only one question.
There will be twenty possible answers but only one correct answer. The contestants must eliminate the incorrect answers to show them the path to victory, but if they eliminate one correct answer it will be game over.
Claudia Winkleman commented: “I am ridiculously excited about One Question. There’s no time limit, no buzzers, no complicated rules. A sofa, a chat, just one question that could win our players £100,000. Not only that, we give them the answer.
