Fans have been gripped by the thriller - which starred Katherine Kelly as lecturer Leah Dale and Molly Windsor as student Rose Vaughan - as it played out on ITV across four nights this week, but the station have confirmed there has been "no talk" of extending its success with another run of episodes in the future.

An ITV spokesperson told The Sun newspaper's Bizarre TV column: "Cheat was conceived as a self-contained four part drama.

"There's been no talk of another season as it was only ever planned as a standalone series."

The confirmation comes after Katherine previously admitted she didn't think another series was likely.

Speaking about the possibility, she said: "It's never even been mentioned.

"As you'll see on Thursday night, we don't hold anything back. So it would be the first I've ever heard of it."

The 39-year-old actress previously insisted she wasn't worried about the success of the show because she knows ratings are impossible to predict.

She said: "You can never predict the popularity of a show and I actually feel like it's none of my business how well it does."

The star - who played Becky McDonald on 'Coronation Street' for six years until 2012 - also shrugged off the idea that her role in the gritty drama could turn her into a sex symbol as she insisted she and her co-stars were "not interested" in the response to the programme.

She added: "We're not interested for us as actors about how this is going to come out. We're not thinking: 'Yeah, I'm going to look really sexy in this.' "
