Channel 4 is combining ‘The Traitors’ and ‘Celebrity Big Brother’ into new show ‘Josh Must Win’.

The broadcaster has created a blend of both programmes with a new psychological strategy gameshow, which is centred around a fake reality show ‘The Favourite’, which sees a cast of larger than life ordinary people striving to be the most popular.

However, a second show – featuring host Nick Grimshaw and stars Pete Wicks, Amber Gill and Vicky Pattison – is actually happening away from the main group.

Across the eight episodes, the celebrities have to do whatever they can to make sure one man leaves ‘The Favourites’ as the winner.

E4’s commissioning editor Mel Bezalel said: “At E4, we’re completely obsessed with reality that drives viewing on All 4, and we’re excited about taking the genre in a completely (and sneaky) new direction.

“This is a show that engages celebrities in an entirely different way, using their unique skillset and experiences to manipulate gameplay – with entertaining and surprising results. This is a TV event not to miss.”

The show has been described as a “buy-one-get-one free” format “unlike anything we’ve seen before”.

An insider told The Sun newspaper’s TVBiz column: “‘The Traitors’ has shown how something a little more intellectual, offering a twist on the standard reality genre, can really fly.

“Bosses hope Josh Must Win will similarly shake things up and capture viewers’ imagination.”

The stars involved will have to “do everything they can” to impact the game.

The source added: “The celebs will do everything they can to influence the game — by setting tasks, introducing twists and using all they’ve learnt about reality shows and popularity to ensure Josh’s triumph.

“Of course the bigger picture is a look at what it takes to be popular today.

“Is it the dry wit of ‘Big Brother’ winner Jordan Sangha? Or the baby-faced innocence of The Traitors’ Harry Clark?”

Other stars – such as Gemma Collins – will feature throughout the eight part run.

‘Josh Must Win’ is coming to E4 next month.
