[6] "We came up with the idea about two years ago and tried it out on our friends - we played it out in a room upstairs at our local pub," Dec said.

"[7] Paul Jackson, director of entertainment and comedy for ITV, said: "We're delighted to be working with Ant and Dec on this promising new format - but I'm sure the boys won't mind me saying that the real stars of this show are the contestants who have got to be consummate performers if they want to win the million.

Each episode begins with "The Grilling," a segment recorded one day earlier, in which the contestants are brought together to introduce and talk about themselves.

They may tell the truth or lie as they see fit, with on-screen prompts indicating honesty or deception for the home viewers' benefit, and clips of their reactions to one another's claims (recorded after the Grilling is complete) are interspersed throughout the segment.

Contestants have three seconds to lock in their responses, starting after the question and choices have been read, and receive £500 per correct answer.

On-screen prompts and a leaderboard are used to show the contestants' performance to the viewers, and at the end of the round, Ant & Dec ask each person how they think they did.

In the event of a tie for last place, the contestant who answered the round's questions in the slower total time is eliminated.
