Here Entertainment Online rounds up everything you need to know about The Celebrity Traitors hosted by Claudia Winkleman.

When does The Celebrity Traitors start on BBC One and iPlayer?

Episodes will air twice a week, every Wednesday and Thursday at 9pm, giving viewers a double dose of treachery. And according to host Claudia Winkleman, the celebrities are in for a brutal ride.

"We're incredibly lucky these brilliant people have said yes. I'd love to say we'll take it easy on them and they'll just wander round the castle and eat toast for a couple of weeks but that would be a lie," she said.

Who is in The Celebrity Traitors 2025?

BBC bosses have pulled together a jaw-dropping line-up for the show's first-ever celebrity edition.

Here's who'll be facing Claudia — and each other — in the castle:

From comedians to campaigners and sporting legends, it's a line-up packed with personalities who'll no doubt bring chaos, charm and cunning.

What's the prize for The Celebrity Traitors?

Unlike the civilian version, the famous contestants won't be pocketing the prize money themselves.

Instead, the group will be scheming, betraying and bluffing their way through the castle to win up to £100,000 for a charity of their choice.

Expect alliances, shock betrayals and emotional reveals as the Faithfuls try to unmask the Traitors among them — before it's too late.

Is The Celebrity Traitors: Uncloaked back?

For superfans, there's even more to enjoy. Comedian Ed Gamble returns to host The Celebrity Traitors: Uncloaked, the official companion podcast — and this time, he's heading inside the castle itself.

He'll be sitting down with the banished and "murdered" celebrity contestants to spill secrets, expose Traitors, and uncover every shocking twist as it happens.

You can catch The Celebrity Traitors: Uncloaked on BBC Sounds or watch it on BBC iPlayer from 8 October.
