The Celebrity Traitors

The Celebrity Traitors is a spin-off of the British version of the reality television series The Traitors. It premiered on BBC One on 8 October 2025. Claudia Winkleman presented the series.

Following the premise of the parent series, the show features a group of contestants participating in a social deduction game similar to Mafia or Werewolf, set in and around Ardross Castle in Scotland. A small group of contestants is chosen as the titular "Traitors," and must work together to eliminate the other contestants to win a grand prize. The remaining contestants are the "Faithful" and are tasked to discover and banish the Traitors by voting them out to win the grand prize. Unlike the main series, the celebrity players are playing on behalf of a charity of their choice.

In August 2024, the BBC confirmed that The Celebrity Traitors had been commissioned, along with two more series of The Traitors, the first of which aired in January 2025. Speaking at the Edinburgh International Television Festival, Kalpna Patel-Knight, the BBC's head of entertainment, said: "The Traitors has well and truly established itself as an unmissable highlight of the year and the news of a fourth outing, alongside a brand new celebrity version coming to the BBC, will take the series to a whole new level. In April 2025, it was confirmed that the show would air in the autumn of that year, with October 2025 later specified.

Filming for the series began on 22 April 2025 at Ardross Castle and concluded the following month, consisting of 9 episodes due to air over four weeks from 8 October to 6 November 2025. Following the cast announcement, host Claudia Winkleman said "We're incredibly lucky these brilliant people have said yes. I’d love to say we'll take it easy on them, and they'll just wander round the castle and eat toast for a couple of weeks - but that would be a lie."

Following the format of the original version of the show, a group of celebrity contestants arrives at a castle in the Scottish Highlands where the members will remain for the duration of the game in order to win up to £100,000 for a charity of their choice. On the arrival day, host Claudia Winkleman picks a small number of contestants to be "Traitors". The rest are automatically called "Faithful". The television audience knows which players have been chosen as Traitors, but the Faithful do not know their number or identity.

At the end of each day, all contestants meet at a Round Table to discuss who they think are Traitors. They then cast votes that are revealed one by one. The person with the most votes is immediately banished, and reveals their identity before leaving. On most nights, the Traitors meet in private and agree to "murder" one Faithful who will leave the game immediately. The remaining Faithful players only discover who has been murdered at breakfast the next morning.

Each day, the group participates in missions to win money for the prize fund which can reach £100,000 by the end of the game. During the missions, contestants may also win a shield that awards that player immunity from being murdered that night, but not from being banished. In some cases, contestants have the right not to disclose whether they won the shield, or to inform only certain chosen players.

After the final Round Table, the remaining players (usually four) gather at the Fire of Truth and participate in the End Game. The group is given an opportunity to end the game by unanimous vote. Any vote to continue will lead to another immediate banishment vote. When a unanimous decision is reached to end the game — or when there are only two players left — the remaining players reveal whether they are Faithful or Traitors. If they are all Faithful, they will share the prize fund for their charities; however, if any of these final players are Traitors they will share the prize fund amongst themselves for their charities.
