Love Island may be the most watched series in ITV2's history but not everyone is a fan.

Former Ofsted chief schools inspector Sir Michael Wilshaw described himself as "absolutely appalled" by the reality show, in which contestants try to form convincing relationships with each other to win £50,000 in prize money.

And it took only five minutes for Sir Michael, who led Ofsted from 2012 to 2016, to draw his conclusion.

"I saw five minutes of it the other day and was absolutely appalled," he said at the Festival of Education at Wellington in Berkshire.

"It is a sad reflection of today's education system," he added in response to a question from host Piers Morgan about whether the series is a threat to education.

The latest series of the show, which sees contestants booted off the island if they cannot find a pair or couples voted off by the public over their popularity, began on June 4 and screens for an hour every night except Saturday.

Love Island makes compulsive viewing for many - but is sneered at by some for the apparent ignorance shown by contestants to major current affairs issues.

Viewers poured scorn on islander Hayley Hughes after she wondered whether Brexit meant we "won't have any trees" and said she did not know what an earlobe was.

During the talk at the Festival of Education, Sir Michael also said that British schools are mediocre, and called for a ban on mobile phones for pupils.
