Former contestants Sophie Gradon, 32, and Mike Thalassitis, 26, both killed themselves after appearing on ITV2's popular reality TV show

Reality shows were already under intense scrutiny after the Jeremy Kyle show was axed after a guest's suicide and Ofcom introduced strict new rules

Caroline Flack's tragic death could lead to ITV bosses pulling the plug on Love Island after she became the third person associated with the show to take their own life.

The hugely popular money-spinner had already been under intense scrutiny following the suicides of former contestants Sophie Gradon, 32, and Mike Thalassitis, 26, prompting calls for producers to take more care of its stars.

Flack's death will reignite concerns over the support that the broadcaster shows to those suffering mental health problems and the perceived lack of support provided by production bosses.

Caroline Flack hosted ITV's Love Island. The presenter, 40, killed herself, a lawyer for the Flack family confirmed

'ITV talk about duty of care but there was little to no support for her,' a source close to Flack told The Sun.

'She went from hosting one of the most popular shows on TV to be effectively cast out.'

Following the tragic news, ITV pulled last night's highlights episode of Love Island: Unseen Bits that was due to air at 9pm on ITV2.

The programme announcer said: 'In light of today's sad news we're replacing tonight's episode of Love Island: Unseen Bits with a double bill of You've Been Framed.'

However it has not known whether Love Island will air on Sunday night as scheduled.

Amid growing criticism of the show, ITV released an updated set of ‘duty of care’ guidelines last May ahead of the show’s fifth season. Provisions included a minimum of eight therapy sessions for each Islander on their return home, as well as ‘proactive contact’ from the team for 14 months afterwards.

The production team also worked with Dr Paul Litchfield, a former government Chief Medical Officer, in a bid to ‘evolve and enhance’ their care arrangements.

Despite the increased focus on the wellbeing of contestants, the show’s bosses will now face questions about the support they showed Ms Flack during her own mental health troubles.

They have already faced claims from within the industry that the presenter was cut adrift after she was charged with assaulting her boyfriend, Lewis Burton.

She 'stepped down' from her role hosting the show in he wake or her arrest, losing her estimated £1.2m salary in the process. It remains to be seen what help the broadcaster gave her.

Her management team said in a statement last night that Caroline had been 'vulnerable' in the wake of her arrest.

She had been due to stand trial in weeks accused of assaulting her partner Lewis Burton, who in December accused her of hitting him with a lamp before he later backtracked on these claims.

Many on social media have called for Love Island to be axed following the death of presenter Caroline Flack and contestants Sophie Gradon and Mike Thalassitis.

Giving evidence at the inquest, Police Constable Emma Clauson said: 'I looked through the notebook which was a sort of combination of a diary and letters and positive thoughts.

'At the back of the diary was a number of notes that had been addressed to his family.'

The inquest heard toxicology results showed there was cocaine, alcohol, paracetamol and antidepressants in his system at the time of his death.

Strictly Come Dancing also paid tribute to Flack after she won the show with Pasha Kovalev in 2014

Flack's death follows the suicides of 2017 contestant Mike who was found dead in a park near his north London home in March last year where he left notes to his family making clear his intention to kill himself.

He was found by a jogger in Church Street Recreation ground next to Haselbury Road in the north London borough where he lived, shortly before 9.30am on March 16 2019.

Former Love Island contestant Montana Brown said Mr Thalassitis had been in a ‘dark place’ in the months before his death.

An officer who attended the scene said a black notebook had been found near where he died.

Her body was found at her home in Ponteland, Northumberland, by her boyfriend Aaron Armstrong, who killed himself 20 days later.

The death of Mr Thalassitis prompted calls from Health Secretary Matt Hancock for reality shows to do more for competitors once they have become famous.

Earlier in 2019, a coroner in Tyneside issued a warning about mixing alcohol and cocaine after another Love Island star, Miss Gradon, hanged herself having consumed both substances.

Coroner Eric Armstrong said research in the US said the combination was known to make someone 16 times more likely to kill themselves.

Miss Gradon was found at her home in Ponteland, Northumberland, by her boyfriend and his brother in June 2018.

Her boyfriend, Mr Armstrong, was found hanging three weeks later, having also taken cocaine and alcohol, and the coroner made a similar ruling at the inquest into his death.

The couple were not staying together on June 19, the night before she was found, because each was looking after their parents' dogs, but they had exchanged loving messages.

Twitter users have called for Love Island to be axed and claimed 'social media and trolls have taken another life'

Sophie, who took part in the 2016 series, died in June 2018 after struggling with depression.

He was concerned when he did not hear from her on June 20 and went round with his brother Ryan and they broke in when they looked through the living room window.

They found her in the living room with her mobile phones nearby, and attempts to give her CPR continued until paramedics arrived.

Detective Sergeant Neill Jobling told the inquest Miss Gradon had previously had mental health issues, including low self-esteem and anxiety, and had been prescribed medication for it which she was still taking when she died.

MPs launched an inquiry into reality TV shows last May after The Jeremy Kyle Show was permanently axed by ITV following 'humiliated' father, Steven Dymond's, suspected suicide after appearing on the show with his former girlfriend.

The Department for Digital, Culture, Media & Sport Committee announced the probe after Mr Dymond, 63, was found dead at home in Portsmouth.

Scrutiny increased when a number of former guests came forward to criticise the 'lack of aftercare' on the programme.

DCMS committee chairman Damian Collins said as the inquiry was launched: 'There needs to be an independent review of the duty of care TV companies have to participants in reality TV shows and the DCMS select committee has decided to hold an inquiry this summer into these issues.'

But Love Island boss and the chief executive of ITV tried to dismiss fears that the suicides were linked to the show.

She said it was 'strange' to link the former contestants' suicides with the show.

Dame Carolyn McCall, 57, was speaking to Radio 4's Today programme in July last year as it was announced the show would run for two series in 2020.

Dame Carolyn was asked why Love Island was not being cancelled like The Jeremy Kyle Show.

She said: 'It wasn't about that particular thing, it was the circumstances around it.'

She added: 'I also think that what happened on Love Island, tragic as it is for anyone who takes their life, it's a terrible thing.

'Mind and the Samaritans tell the public constantly not to simplify links, and I'm afraid that's what media does.

'The two contestants, who were very popular contestants - Sophie and Mike - there was nearly a two-year gap for each of them and they did lots and lots of other things after Love Island, so I think it's a strange thing for you to bring up to be honest.'

Dame Carolyn went on to explain the decision to provide counselling for the contestants on the show both during and after their appearance.

Since the two Love Island stars' tragic deaths, ITV has evolved its aftercare policy for Love Island contestants.

Bosses have promised to support the contestants' families both before and after the show amid recent reality deaths.

The ITV2 show has written an extra clause in the stars' contracts which vows to help the loved-ones of cast mates, as well as the contestants themselves.

In a statement last year, they wrote: 'The production team have continued to evolve their processes with each series, as the show's popularity has risen and the social and media attention on Islanders has increased.

However friends of Ms Flack – who had fronted the programme since 2015 – complained the broadcaster had failed to back her in the same way it had Ant McPartlin after his drink-drive conviction.

Yet criticism has not been confined to Love Island. Last May, ITV axed The Jeremy Kyle Show, which had screened more than 3,300 episodes, after a guest died in a suspected suicide.

An inquest heard Steve Dymond, 63, feared ‘repercussions’ after failing a lie detector test on the show. He took the test to convince his fiancee Jane Callaghan that he hadn’t been unfaithful.

Ofcom announced in July that it would implement stringent new guidelines to protect reality TV stars amid a raft of complaints from worried viewers.

The media watchdog proposed new rules to protect participants in TV and radio shows, and to ensure they are properly cared for by broadcasters.

Ofcom cited the 25,322 complaints it received about Celebrity Big Brother in 2018 after Roxanne Pallett claimed that her fellow housemate Ryan Thomas had physically assaulted her.

Most complainants expressed concern about the personal impact on Thomas and others specifically expressed concern about Pallett's wellbeing.

Caroline posted a final series of snaps on Instagram on Thursday with her dog Ruby just two days before she was found dead in her London flat after apparently taking her own life

It also referred to the 7,912 complaints in August 2018 after Kim Woodburn appeared on Loose Women.

The majority of complainants expressed concern that the presenters had humiliated Woodburn and caused her unnecessary distress.

It also cited the 2,644 complaints received in July 2018 about Love Island participant Dani Dyer being shown a video of then-boyfriend Jack Fincham reacting to his former partner entering Casa Amor.

The regulator said it would add two rules to the existing Broadcasting Code, which would protect the welfare of participants in reality shows, documentaries, news and current affairs, phone-ins, quiz shows, talent contests and other forms of factual and entertainment programmes, but not drama, sitcoms or soaps.

The new rules state that 'due care must be taken over the welfare, wellbeing and dignity of participants in programmes'.

The second states that 'participants must not be caused unjustified distress or anxiety by taking part in programmes or by the broadcast of those programmes'.

The proposed rules reflect the fact that very different forms and levels of care may be appropriate, depending on the person participating, a programme's format and the nature of the participation, Ofcom said.

The watchdog added that it wishes to ensure that the proposed new rules do not make programmes less likely to feature people with vulnerabilities, as there is a public interest in their representation.

Tony Close, Ofcom's director of content standards, said: 'People who take part in TV and radio shows must be properly looked after by broadcasters, and these rules would ensure that happens.

'These new safeguards must be effective. So we're listening carefully to programme participants, broadcasters, producers and psychologists before we finalise them.'

Caroline's management team hit out at the decision to push ahead with her court case. In a statement, Francis Ridley of Money Talent Management, said: 'We are devastated at the loss of our client and friend Caroline Flack.

'An immensely talented young woman who was at the top of her game professionally and loved by television viewers across the country. In recent months Caroline had been under huge pressure because of an ongoing case and potential trial which has been well reported.

'The Crown Prosecution Service pursued this when they knew not only how very vulnerable Caroline was but also that the alleged victim did not support the prosecution and had disputed the CPS version of events.

'The CPS should look at themselves today and how they pursued a show trial that was not only without merit but not in the public interest. And ultimately resulted in significant distress to Caroline. Our thoughts are with Caroline's family at this time.'

An ITV spokeswoman said: 'Everybody at Love Island and ITV is shocked and saddened by this desperately sad news. Caroline was a much loved member of the Love Island team and our sincere thoughts and condolences are with her family and friends.'

A TV series called The Surjury, featuring Flack as the host, will no longer air on Channel 4, the broadcaster said.

A Channel 4 spokeswoman said: 'We are shocked and saddened to hear the tragic news about Caroline Flack. Our deepest sympathies go out to Caroline's family and friends.

'Under the circumstances, we have decided not to broadcast The Surjury.'

The presenter announced she was set to host the controversial show back in October, which was expected to see young people convince a jury of peers and experts to approve of their life-changing operations.

Strictly Come Dancing also paid tribute to Flack after she won the show with Pasha Kovalev in 2014.

In a post on Twitter, the BBC series released a statement reading: 'The entire Strictly Come Dancing family are heartbroken to hear this incredibly sad news.

'Caroline had an infectious energy and passion for dance, she shone brightly in the Strictly ballroom every week and became an incredible champion.

'Words cannot express our sadness, she was simply one of a kind. We are sending our love to all her family and friends during this difficult time'.

This Morning presenter Eamonn Holmes, 60, tweeted: 'Caroline Flack .... Dear God. Shocked beyond belief. May she have found peace. #Rip'

He added: 'Has to be repercussions for Love Island now surely?'

It comes after singer Boy George slammed the Crown Prosecution Service for charging Flack with assaulting her boyfriend Lewis Burton.

The Culture Club lead singer tweeted: 'I hope all of you who attacked Caroline Flack even when her partner said he wanted no charges feel some sorrow today. This did not need to happen.

'This is devastating news! And yes, I hope the @cpsuk feel even deeper sorrow.'

Aftercare: Since the two stars' tragic deaths, ITV has evolved its aftercare policy for Love Island contestants (late Love Island star Mike pictured in October 2018)

Sophie Gradon, 32, and Michael Thalassitis, 26, hanged themselves after going on Love Island Sophie Gradon, 32, from Newcastle. Died on 20 June, 2018 The former Love Island contestant hanged herself in her home in Newcastle after drinking alcohol and taking cocaine two years following her appearance on the ITV2 show. The former reality star and Miss Great Britain, 2009, was tragically found dead by her boyfriend Aaron Armstrong, who shared a picture of them together with the words: 'I will never forget that smile I love you so so much baby your my world forever ever and always'. Ms Gradon's inquest heard the former contestant had been battling with crippling anxiety and depression in the months leading up to her death.
