The boss of ITV has described the death of broadcaster Caroline Flack as "unbelievably tragic", and said that the company is "absolutely focused" on making its duty of care "world class" for those appearing on its programmes.

The Press Association reports that Carolyn McCall, who has been the Chief Executive of ITV since 2018, and previously served as the Chief Executive of EasyJet until 2017, addressed the death of former Love Island host Flack, who died last month, at a conference in London on Thursday.

"I think the thing about Caroline Flack is that ITV are absolutely devastated by what happened to her," she said.

"So many people at ITV knew Caroline, including me, and it was unbelievably tragic.

"I think that we can never know what is behind suicide. It is not in any way simple. It is a very, very complex thing."

"We take advice from [mental health charities] Samaritans and Mind and we will continue to do that," McCall explained at Enders' and Deloitte's Media And Telecoms 2020 and Beyond conference.

The deaths of former Love Island contestants Sophie Gradon and Mike Thalassitis, and The Jeremy Kyle Show guest Steve Dymond, prompted increased scrutiny of ITV over its aftercare.

"As far as duty of care is concerned, we are absolutely focused on making sure our duty of care is, for both our participants and for our talent, world class. We want to be best in class for that," said McCall.

"I think because we reviewed Love Island last summer, so a few months before last summer's series, Paul Litchfield, who is the former CMO [Chief Medical Officer at BT], works with us, and he made a whole load of recommendations which we have implemented, which is about aftercare, which is about casting, which is about a whole range of things - financial management, social media management.

"Social media is the thing that has gone absolutely ballistic. It has actually only happened in the last three years, because in the first two years [Love Island] was too small.

"It wasn't really a successful programme. It has only really made a big difference in the regionals three years ago on social media.

"We take that very serious and we are actually working with the industry on how we can share all of that and how we can learn and pool our resources, so we can learn from each other. So that is what we are doing."
