ITV said the episode had the biggest audience on a digital channel since the London Olympics on BBC Three in 2012.

The broadcaster also said that the show, which aired from 9pm until 10.35pm last Monday, was seen by a further one million fans on non-TV devices, in addition to the 4.1 million.

The overnight ratings for the show have remained steady in the week and a half since the fourth series kicked off.

Last Monday’s launch was watched by 2.9 million in the overnight ratings, and the most recent episode – which aired on Tuesday – drew an average overnight audience of 2.8 million.

Love Island, which sees hopeful singletons live together in a Spanish villa for weeks on end in order to find love and win a cash prize, has become a hit in recent years for the channel.

The latest episode saw tensions reach fever pitch in the sun-soaked villa, as contestants Rosie Williams and Adam Collard had a row, as did Eyal Booker and Alex George, who are both competing for newcomer Megan Barton Hanson’s affections.

Love Island continues at 9pm on ITV2.
