The fourth series of The Traitors was first broadcast on BBC One on 1 January 2026. Claudia Winkleman returned to present the series, accompanied by the spin-off show The Traitors: Uncloaked, presented by Ed Gamble. == Production == In August 2024, prior to the beginning of the previous series, it was announced that The Traitors had been renewed for a fourth series. Applications for the series opened on 22 August 2024, before closing on 28 March 2025. Filming for the series began in June 2025. The first teaser for the fourth series aired at the end of the final of The Celebrity Traitors, which featured a figure wearing a Traitors' cloak carrying a lantern walking through a forest at night, whilst "Heart of Glass" played in the background. The series began on 1 January 2026. == Contestants == The 22 contestants competing in the series were revealed at midnight on 1 January 2026, the day of the show's launch. Amongst the contestants were a mother and daughter, Judy and Roxy, who did not reveal their relationship to the other players. Additionally, Netty and Ross were old acquaintances, who did not know each other would be present and were selected for the series independently. In the first episode, Winkleman revealed that one contestant would be selected as a "Secret Traitor", whose identity would be hidden from both the audience and the regular Traitors. Each night, they would provide the Traitors with a shortlist of Faithful to murder. The "Secret Traitor" is visually represented on screen as an unidentified figure dressed in a red cloak. Contestants were therefore only initially identified as Faithful by appearing on murder shortlists selected by the Secret Traitor, or after being banished. In episode 3, Traitors Stephen and Rachel completed a mission to reveal the Secret Traitor's identity. == Elimination history == Key The contestant’s affiliation is not confirmed yet. The contestant was a Faithful. The contestant was a Traitor. The contestant was murdered by the Traitors. The contestant was banished at the round table.
