Celebrity Traitors returns to BBC One and iPlayer on October 1, opening with an extended episode in which Winkleman selects the Traitors and Faithfuls.

After each episode, The Celebrity Traitors: Uncloaked, hosted by Ed Gamble, will recap and discuss events from the game.

The new series is set in a Scottish castle, featuring celebrities playing a game of deceit to identify traitors who quietly kill players at night.

The first series finale drew 15.4 million viewers, with the spin-off The Celebrity Traitors: Uncloaked averaging 14.9 million, marking it as the biggest TV audience of 2025.

The show originally premiered last autumn with strong viewership, and the spin-off subsequently posted the largest TV audience of 2025.

In the series, celebrities—predominantly Faithfuls—compete to identify traitors who secretly kill players, with a charity prize pot of up to £100,000.

Contestants must uncover hidden Traitors while navigating deception, trust, and strategic eliminations.

The 2025-2026 format continues the mansion-style structure, where Traitors attempt nighttime killings and Faithfuls work to expose them.

The prize remains up to £100,000 for a charity of the winner’s choice, with a lineup including Maya Jama, Michael Sheen, Miranda Hart, James Blunt, and others.

Celebrities in the lineup include Leigh-Anne Pinnock, Maya Jama, Rob Beckett, Ross Kemp, Stephen Fry, James Blunt, Joe Lycett, Miranda Hart, Michael Sheen, among others.

The show’s format centers on high-stakes social deduction, with the first series finale drawing 15.4 million viewers according to the BBC.

Claudia Winkleman teased the season by wearing a jacket emblazoned with 'Faithful' ahead of the return to BBC One and iPlayer.
