Traitors UK 2026 features a red cloak that gives more power than ever before. That's right, as well as the regular traitors that dot the castle murdering as they go, there was a secret traitor, too, that not even the middle management traitors knew the identity of. Don't worry, no spoilers here.
We're now into the final stretch, with just three episodes remaining in season 4, each coming on successive evenings from Wednesday. With the special power of a double vote in the next roundtable to be bestowed by the traitors, who's getting the special prize?

What is happening The Traitors season 4? (SPOILER WARNING)
A new cohort of 22 members of the public will descend on Ardross Castle in the Scottish Highlands to perform a series of mental and physical challenges to win a potential £120,000 prize pot. Each are assigned traitor or faithful – the former can murder the latter, while the latter try to banish the former at the nightly round table. Any traitors left at the end of the game win the money for themselves – if it's only faithful, they share it between them.
It's the ultimate game of strategy and treachery, with lying and cheating actively encouraged, and contestants often concealing their relationships with another contestant or pretending to be Welsh – Charlotte from season 3, we're looking at you.
Stephen and Rachel remain the the traitors in the turret, and they seem to have binned any possibility of recruiting Matthew, who thought he had a deal following a blind meeting with the gruesome twosome. They've got to decide who will get a special dagger that provides a double vote in the next roundtable – do they give it to themselves to guarantee they remain?
Can the remaining faithfuls, who are largely struggling, realize that it's Rachel who has been manipulating them throughout?
Is The Traitors: Uncloaked back too?
Absolutely. Presented by super fan and comedian Ed Gamble, the accompanying visualised podcast will go out on BBC Two immediately after the regular episode on BBC One.
It will, of course, also be available on BBC iPlayer.

What is The Traitors red cloak in season 4?
Oh, it's a biggie. This year, there's a secret traitor – depicted in a red cloak instead of the regular dark green – whose identity is hidden not only from the regular traitors, but also from the watching audience at home.
The secret traitors holds huge power as they select the three-person shortlist for murder every night (they can only pick faithfuls) from which the traitors must pick one. They no longer have free rein and are, essentially, middle management.
That means the guessing has started in living rooms across the world as people try to work out who it could be.
Early suggestions were Judy, but she's been banished and revealed to be a faithful, and the traitors think it could be psychologist Ellie or professional Welshwoman Fiona.
