Argumental

Participants

The programme was originally chaired by journalist John Sergeant whose post-journalistic career at the time the series began was on the rise due in part to his appearance on the BBC's Strictly Come Dancing. He was joined by team captains Marcus Brigstocke, the host of The Late Edition, and comedian Rufus Hound. Each team captain was accompanied by a guest panellist who have included Jimmy Carr, Sue Perkins, Reginald D. Hunter, Phill Jupitus, Charlie Higson, Johnny Vegas, Lucy Porter, Dara Ó Briain, Sean Lock and Frankie Boyle. From the 2011 series, Sean Lock replaced John Sergeant as presenter, while Seann Walsh and Robert Webb took over as team captains. This coincided with a revamp of the show's set and graphics.

Format

Each episode comprises a series of rounds in which each team takes its turn debating a variety of topics, whilst also trying to be amusing. Topics have included: 'recycling is a waste of time' and 'the Royal Family serve no purpose'. After each round the team members often make humorous observations about what has just been said, before the studio audience votes for who they thought put forward the best case. Voting is done by holding up a red or blue paddle to vote for the red or blue team respectively. The votes are tallied before the winner of the round is decided. The team that wins the most rounds wins the show.

Rounds

Each episode normally contains 5 rounds. Sometimes however some episodes contain 4 rounds with 1 round dropped altogether.

Classic debate

A representative from each team takes their turn to argue for or against a given motion, respectively. After the main arguments have been put forward the teams are invited to discuss the subject further to reinforce their team's argument or attack their opponent's.

Visual aids

Team members try to argue over a topic while incorporating pictures from a slideshow that they have never seen before into their case.

Flip-flop

Each team is given a different topic to argue about in this round. The team representative must argue for the motion until a buzzer sounds at which point they must argue against the motion. The contestant continues to alternate between for and against until the end of round buzzer is sounded. This round does not appear in every episode.

That's a Brilliant Idea

Introduced in series 3, representatives from each team take turns being given a typically nonsensical, illogical or outrageous statement, and have to argue a convincing case for that statement being a good thing, starting each argument with the words "That's a brilliant idea.".

Popular culture round

In series 1, this round was similar to the 'classic debate' round except the topic involves a famous person or celebrity. The person being debated was represented by a life sized cut-out placed in the centre of the performance stage. Past celebrities have included Piers Morgan, Victoria Beckham, Amy Winehouse, Wayne and Coleen Rooney, Simon Cowell and Jeremy Kyle.

Since series 2, this round has not always featured cardboard cut-outs; in some episodes, real-life people (e.g. a body builder) come on stage instead.

Final picture round

This round doesn't involve any arguing per person, alternatively contestants are shown pictures for which they must invent a motion to suit. Unlike the other rounds, both teams remain seated throughout. Like the flip-flop round, this round has not always been included. The audience still votes red or blue.
