They Gave 10 Million People Permission to Watch Someone Lie. And They Can't Get Enough of It.
The man behind The Traitors just revealed what Season 5 looks like — and why this show might outlast all of us.
Think about the last time you trusted someone completely — and then found out you shouldn't have.
That feeling. That specific, stomach-dropping moment. That is the entire product Stephen Lambert has been selling to Britain for four years. And right now, nearly 10 million people are buying it every single week.
Lambert, the chief executive of Studio Lambert and the architect of The Traitors, stepped back onto the campus of the University of East Anglia recently — the same university where he graduated back in 1981 — and said something that should make every reality TV commissioner in the world sit up straight. He isn't slowing down. He isn't coasting. He is already building Season 5.

The Castle Was Never an Accident
Before a single lie is told, before a single contestant trembles at the roundtable, Lambert made one decision that changed everything: Ardross Castle in the Scottish Highlands. Not a hotel. Not a studio. A castle. Fog-draped, cold-stoned, ancient. A place where betrayal feels almost… appropriate.
That atmospheric choice was not luck. It was deliberate production design dressed up as a location decision. The gothic setting does half the psychological work before the cameras even roll — it tells every contestant, and every viewer at home, that the normal rules do not apply here.
Lambert knows this. He described it plainly: the programme was deliberately given "this great gothic setting," and that setting has become as much a character in the show as any contestant who has ever walked through its doors.
15 Million People Watched a Comedian Win. Let That Sink In.
Here is the number that should stop you mid-scroll: more than 15 million viewers, including catch-up, watched Alan Carr be crowned the winner of the Celebrity Traitors edition. Fifteen million. That is not a television show anymore. That is a national conversation.

And before that, nearly 10 million tuned in to watch Rachel Duffy triumph in the fourth series in January. Two different shows, two different winners, one consistent truth — once people start watching The Traitors, they cannot stop.
Lambert's explanation for why is characteristically sharp. He compared it to poker. "People are given licence to lie," he said. And in a world where we are constantly told to be authentic, to be transparent, to show our true selves — there is something wickedly thrilling about watching someone do the exact opposite, brilliantly, on national television.
Why This Show Will Outlast Your Favourite Show
Lambert is not making bold predictions about Season 5 in a vacuum. He came armed with precedent. The Apprentice. Big Brother. Two formats that, by every reasonable expectation, should have faded years ago — and are still running after 25 years.
His argument is precise: the secret to format longevity is not reinvention. It is the tension between familiarity and freshness. "Both repeating, which gives you familiarity, but at the same time it has to offer freshness both in terms of the cast and in subtle changes or twists," he explained.
Translation: don't blow up what works. Find the small levers. Pull them carefully.
For Season 5, that means the castle stays. Claudia Winkleman stays. The social dynamics, the paranoia, the late-night whispers in candlelit corridors — all of it stays. What changes will be subtle. Quietly destabilising. Exactly the way a Traitor would do it.
The Woman in the Cloak
No conversation about this show's success is complete without Claudia Winkleman, and Lambert knows it. He called getting her on board "a stroke of luck" — but anyone who has watched her work knows luck had nothing to do with it.
Winkleman has now presented four full series and one celebrity edition. She is the show's moral compass and its most unsettling presence simultaneously — warm enough to make contestants feel safe, theatrical enough to make them feel doomed. Lambert described her simply: "She's just brilliant."
She will be back for Season 5. That continuity alone is worth more than any format twist Lambert could dream up.
So What Comes Next?
Lambert left UEA without giving away the specifics of Season 5 — because of course he did. He is, after all, a man who has spent years producing a show about the strategic withholding of information.
But the outline is clear. The same dark Scottish castle. The same presenter who makes grown adults look genuinely frightened. The same social pressure cooker that turns ordinary people into either masterful liars or spectacular victims. And somewhere inside that, a small, careful twist that nobody will see coming.
Ten million people are already waiting.
The only question is: are you a Faithful — or are you something else entirely?
