Everything you need to know ahead of the Celebrity Traitors

The first series of the Celebrity Traitors kicks off later, with Sir Stephen Fry, Celia Imrie, Alan Carr and Jonathan Ross among the contestants.

Presenter Claudia Winkleman will welcome 19 famous faces to the Scottish highlands when the 70-minute opening episode launches at 21:00 BST.

Charlotte Church, Kate Garraway, Paloma Faith and Tom Daley are among the other stars who will be sitting at the famous round table.

Ahead of the launch, Winkleman told journalists: "You think you know these people, and then you watch them play this game, and I was awestruck by the way they played it - with empathy, with wit and with real smarts."

The contestants are:

The celebrities will play for a cash prize of up to £100,000.

The exact figure will depend on how they perform in missions throughout the series, where the money can go up or down.

However, unlike the civilian version where the contestants keep the jackpot, the celebrities are playing for their chosen charity.

But they will receive a separate appearance fee for taking part in the series.

The trailer for the Celebrity Traitors shows the celebrities expressing their excitement as they are driven to Ardross Castle in Inverness.

But Winkleman soon tells them: "I know out in the real world you're very important and successful, but here, there is no special treatment."

The teaser also shows the celebrities taking part in their first mission, and sitting at the round table for the first time, wearing their blindfolds.

Looking ahead to the series, the stars also grapple with whether they will be chosen as traitors, or remain faithful.

"Maybe I have got a dark side," says Carr, while Sir Stephen adds: "I don't know what beasts lie within me". Imrie simply says: "I'm here to win."

For the first time, comedian Ed Gamble will take the spin-off show Uncloaked on location to the castle, to interview celebrities as soon as they leave.
