Comedian Alan Carr has been crowned the winner of Celebrity Traitors.
The presenter, 49, burst into tears after he revealed to the remaining faithfuls, comedian Nick Mohammed and historian David Olusoga, that he was a traitor.
Carr also declared that the prize money, which amounted to £87,500, (€98,682.50)will go to a children's cancer charity for neuroblastoma.
The comedian was overcome with emotion after he declared: "I am and have always been a traitor."
He added: "I’m so sorry, it’s been tearing me apart."
He was comforted by Olusoga and Mohammed, who said: "You did brilliantly."
Carr revealed to the faithfuls the identity of the other traitors, Cat Burns and presenter Jonathan Ross, who was banished at a roundtable earlier on in the series, leaving Mohammed to cover his mouth in shock.
The Ted Lasso star said: "Alan Carr. He played an absolute blinder."
Carr said: "What a rollercoaster, how did this happen?
"I was awful at lying and had a terrible poker face and here I am, the winner."
Earlier in the episode the remaining players completed their final mission, which saw them board the Traitors Express steam train in a bid to crack a series of codes to find missing keys and win money for the prize pot before explosives were detonated.
The team of five successfully completed the challenge and added £20,000 to the fund, leaving a total prize pot of £87,500 before facing the first heated roundtable which saw singer Burns banished.
The traitor was eliminated from the game following an alliance between former rugby player Joe Marler and Mohammed, who convinced Olusoga to also vote for Burns.
The remaining players did not know they successfully banished a traitor from the game and faced a second roundtable which saw Marler leave the game after a shock vote from Mohammed, who turned against him after becoming suspicious of the faithful.
The remaining three unanimously decided to end the game, sealing Carr’s fate as the series’ winner.
Throughout the series, Carr and Burns "murdered" a string of faithfuls, including actress Celia Imrie, comedian Lucy Beaumont and Olympic diver Tom Daley, while faithfuls including actor Sir Stephen Fry, presenter Clare Balding and actor Mark Bonnar fell under suspicion and were banished by their fellow contestants.
Since the UK version began in 2022, millions of fans have watched The Traitors on the BBC and it has picked up a Bafta TV Award for best reality and constructed factual programme and best entertainment performance for host Claudia Winkleman.
This was the first UK celebrity series of the popular reality show and has been a ratings hit for the BBC, attracting more than six million viewers when it launched on October 8.
Elsewhere, the comedian's agent booked him into events two weeks into filming The Celebrity Traitors as they did not think he would get far.
Speaking about the victory on the visual podcast, Uncloaked, Carr said: "It still hasn’t sunk in, it’s insane."
Asked if he expected to get so far, he said: "No, no, no, no, I did not even think I would get this far.
"My agent had actually booked in things for the second week saying, 'With your poker face you’ll be out’.
"I go through customs I start sweating, when I go to a newsagents and it says no shoplifting.
"I’ve got the worst poker face going, it’s a tug of war with my face."
Carr has also said that humour was his "secret weapon" in the castle and that he would "often deflect scrutiny and make a gag about something which would then throw everyone off the scent".
"My sense of humour was probably more useful to me than a shield," he said.
Carr added: "So I’m really, really proud, I can be a chameleon, I can chat, I can lie when I need to. Idiots can do well."
Speaking about the emotional reveal and his chosen charity, Carr said: "I think all the deceit, the lying, the murdering of Paloma (Faith) and Celia (Imrie) had all taken its toll and then I think it dawned on me that I had won such a huge amount for my charity, Neuroblastoma UK.
"The charity is so close to my heart that it all became a bit too much. Hopefully when people see how upset I was they won’t feel so bad that I killed all those national treasures.
"I told one person at the charity and they started crying, so that gives you some idea of how important this money will be to them.
"Neuroblastoma is such a cruel disease, and this money will literally save lives. It’s a charity and disease that no one has really heard of so with the viewing figures being what they are it’s going to be so good for the charity."
