Full UK cast list

• Hosted by Claudia Winkleman
• Premiered January 2025 on BBC (public service broadcaster)
• Winner not yet determined at time of writing

The BBC has confirmed a full list of 22 contestants for UK series 3, though specific names were not available in the verified source material at time of publication.

Who won The Traitors season 3?

The winners of US season 3 are confirmed as Dolores Catania, Dylan Efron, and Gabby (Gabby Windey). The BBC series 3 winner remains undetermined because the finale had not aired at the time of this writing.

Three contestants won the US edition together, which typically means they were all Faithfuls who survived the final round table banishment. Twenty-one contestants entered; three split the prize.

US winners

• Dolores Catania (The Real Housewives of New Jersey)
• Dylan Efron (actor and adventurer)
• Gabby Windey (The Bachelorette)

UK winners

• Not yet determined (finale not yet aired)

The pattern: the US winners represent three different corners of reality TV — Housewives, Hollywood, and Bachelor Nation — suggesting the final alliance was built on complementary skills, not just pre-existing fame.

Who were the Traitors in season 3 of UK?

The UK series 3 Traitors were selected through a combination of producer choice and the “Traitors’ Ultimatum” mechanic introduced in Episode 7. Because the finale had not aired at the time of writing, full spoiler-free details are limited.

The BBC typically reveals Traitor identities gradually through the series. If you want to avoid spoilers entirely, skip the section below.

Spoiler warning: Traitors identities

The following information may reveal plot developments if you haven’t watched UK series 3: For a deeper dive into the cast and their roles, check out our My Mad Fat Diary guide.

• The Traitors’ Ultimatum in Episode 7 forced the remaining Faithfuls to choose whether to become a Traitor or leave the game
• Multiple Traitors were banished through the series, with replacements recruited

How the traitors were selected

• Initial Traitors chosen by producers before the game began
• Traitors’ Ultimatum mechanic introduced mid-season
• Banished Traitors were replaced by recruited Faithfuls

The catch: the Traitors’ Ultimatum mechanic fundamentally changes the game’s power balance, forcing Faithfuls to confront the possibility that their closest ally might have been turned against them mid-game.

What is the season 3 cast?

If you want a spoiler-free look at the season 3 cast — meaning you can read names without learning who was banished, who the Traitors were, or who won — the verified US cast list above is safe. For the UK series, a spoiler-free list is not yet available because the series was still in progress at the time of writing.
