That's according to ITV executive Paul Mortimer, who claims working conditions behind the scenes are "really quite tough" for producers while they set about making the popular ITV2 show - recently won by Dani Dyer and Jack Fincham - on the sun-soaked island of Majorca.

He said: "They've been working 14-hour shifts in conditions that are really quite tough.

"In the production village, it looks like you're in a war zone."

ITV exec Angela Jain added: "Some 200 people work their butts off, in 37C heat in an old concrete factory."

The latest series was hit with allegations that producers had manipulated certain situations, and Paul and narrator Iain Stirling admitted the producers don't just let the contestants sit around sun-bathing all day.

Speaking at the Edinburgh TV Festival's 'Love Island' masterclass, Paul is quoted by the Daily Mirror newspaper as saying: "Of course it has the hand of a producer. We are making a TV show."

Iain Stirling added: "If you left 20-somethings to their own devices they would just lie by the pool, getting a tan."

But the show certainly still seems to be popular with 'Love Island' wannabes, after more than 25,000 people applied to be on next year's series within a week of the villa's doors shutting on season four.

Host Caroline Flack recently said: "If you think you have what it takes to flirt outrageously with people like this lot then applications for next year are now open. We've already had 25,000 people register."
