Celebrity Traitors Series 2: Full Cast Confirmed for BBC's Biggest Show
The BBC has confirmed the full lineup for the second series of The Celebrity Traitors, and it is, by any measure, a remarkable assembly of talent. Twenty-one of Britain and Ireland's most recognisable faces — from Oscar-nominated actors to beloved comedians, broadcasters, and musicians — will head to a castle in the Scottish Highlands to compete in the game of deception that became the biggest television event of 2025. The first celebrity series attracted an average audience of 14.9 million viewers, making it the most-watched programme of the year.Background
The Traitors, hosted by Claudia Winkleman, arrived on BBC One in 2022 as an adaptation of a Dutch format and quickly established itself as one of the most compelling reality programmes in British television history. The format is deceptively simple: a group of players must identify the "Traitors" hidden among them, while the Traitors attempt to eliminate the "Faithfuls" without being caught. The tension, the psychology, and the sheer unpredictability of the game proved irresistible to audiences.
The civilian series ran for three successful series, but it was the decision to cast celebrities — with their existing public profiles, complex relationships, and the added dimension of playing for charity — that transformed the show into a genuine cultural phenomenon. The first Celebrity Traitors series, broadcast in early 2025, was won by comedian Alan Carr, who navigated the game with a combination of charm and strategic acuity that delighted viewers. The series finale attracted over 16 million viewers, a figure that no other programme had matched in years.
The BBC's decision to commission a second celebrity series was announced within weeks of the first series ending, reflecting the extraordinary commercial and cultural success of the format. The challenge for the production team was to assemble a cast that could match — and ideally exceed — the chemistry and drama of the first series.
Key Developments
The confirmed cast for series two is a genuinely eclectic mix. The acting contingent is led by Richard E. Grant, the Swaziland-born British actor known for his roles in Withnail and I and Can You Ever Forgive Me?; Michael Sheen, the Welsh actor and activist who previously appeared in Good Omens; and Bella Ramsey, who rose to global prominence in The Last of Us. They are joined by Myha'la from Industry, Julie Hesmondhalgh from Coronation Street, Sharon Rooney from My Mad Fat Diary, and Sebastian Croft from Heartstopper.
The comedy lineup is equally strong: Miranda Hart, James Acaster, Joe Lycett, Romesh Ranganathan, and Rob Beckett will all be competing, alongside Irish comedian Joanne McNally, whose podcast My Therapist Ghosted Me has made her one of the most popular comedians on the island of Ireland. Love Island host Maya Jama, former Little Mix star Leigh-Anne Pinnock, singer-songwriter James Blunt, model and actor Jerry Hall, broadcaster Amol Rajan, mathematician Professor Hannah Fry, and content creator King Kenny complete the lineup.
The BBC confirmed that the prize fund remains at up to £100,000 for each celebrity's chosen charity. Filming has already taken place at the same Scottish Highlands castle used in previous series, and the show is expected to air later in 2026.
Why It Matters
The Celebrity Traitors has become one of the most significant cultural events in British broadcasting, and its second series arrives at a moment when the BBC is under sustained pressure to justify its licence fee funding model. The show demonstrates that public service broadcasting can still produce content that commands genuinely mass audiences in the streaming age — a point the BBC has been making forcefully in its negotiations with the government over the future of the licence fee.
The inclusion of Joanne McNally in the cast is particularly notable from an Irish perspective. McNally is one of the most successful Irish comedians of her generation, and her appearance on one of the BBC's flagship programmes reflects the increasingly porous boundary between British and Irish entertainment culture. Unlike previous generations of Irish performers who felt they had to relocate to London to build a UK profile, McNally has built a substantial British audience while remaining based in Dublin. The show's Scottish setting also gives it a distinctly Celtic flavour that resonates with audiences across the UK and Ireland.
Local Impact
The Celebrity Traitors is one of the most-watched programmes in Northern Ireland and the Republic of Ireland, where it airs on BBC One and RTÉ respectively. The inclusion of Joanne McNally will generate significant additional interest on the island of Ireland, and her performance in the game will be followed closely by Irish audiences. For the BBC's Northern Ireland operation, the show's success is a reminder of the value of network programming that resonates across all parts of the UK. Belfast's own entertainment scene — from the Waterfront Hall to the SSE Arena — has benefited from the increased profile of Irish and Northern Irish performers in recent years, and McNally's appearance on Celebrity Traitors is likely to boost demand for her live shows in the region.
What's Next
The BBC has not yet confirmed a transmission date for the second series, but industry sources suggest it will air in the autumn of 2026. Claudia Winkleman is confirmed to return as host. The civilian series of The Traitors is also expected to return for a fourth series, with casting currently underway. The show's international versions — including successful adaptations in the United States, Australia, and the Netherlands — continue to expand, with the BBC's format now one of the most valuable in global television.
