The Jeremy Kyle Show guest who died following filming was a 63-year-old man who took his own life, according to reports.
The man has been named as grandfather Steve Dymond.
A spokesman for Gosport coroners office said: HM Coroner has ordered a post-mortem to be carried out and is awaiting the result. An inquest is likely to be opened into the death within the next few days.
Mr Dymond took a lie-detector test to convince fiancee Jane Callaghan he had not cheated but they split after he failed, according to The Sun.
The ITV daytime show was taken off air indefinitely following Mr Dymond’s death, which happened a week after he filmed the show.
The controversial programme has been criticised by MPs for failing to look after its guests, as calls mount for it to be cancelled for good.
Ms Callaghan said Mr Dymond had been quietly struggling, but praised the show’s team for their after-care efforts.
She told newspaper: They were brilliant. They were there when he needed help. They were really persistent in offering him help.
Ms Callaghan said that just before they went on the show, Mr Dymond had convinced her he had not cheated.
She said the pair split up after the show, reportedly filmed on 2 May, and last saw him four days later before Mr Dymond was found dead last week.
She added: I can’t see Steve taking his life without explaining it to me first.
But he always said he would never love someone else.
Damian Collins, chairman of the commons digital, culture, media and sport committee, said TV companies have a duty to care to the people who take part in their programmes, while Tory MP Simon Hart, who also sits on the committee, described the Jeremy Kyle Show as car-crash TV which revels in people’s terrible misfortune and sometimes their vulnerabilities.
Charles Walker, vice-chair of the parliamentary group on combating suicide and self-harm, called on ITV to stop commissioning the show
Mr Walker demanded a crackdown on programmes that put people under a huge amount of pressure and wait until they go pop.
The episode featuring the guest who died will be submitted for a review due to the seriousness of this event, ITV said.
A spokesman for the channel said: Everyone at ITV and The Jeremy Kyle Show is shocked and saddened at the news of the death of a participant in the show a week after the recording of the episode they featured in and our thoughts are with their family and friends.
ITV will not screen the episode in which they featured.
Given the seriousness of this event, ITV has also decided to suspend both filming and broadcasting of The Jeremy Kyle Show with immediate effect in order to give it time to conduct a review of this episode of the show.
The show has run on ITV since 2005 and features Kyle solving the problems of his guests through on stage mediation – which often involves a lie detector.
ITV’s support for its reality stars has also come under scrutiny following the deaths of two former Love Island contestants.
Sophie Gradon, 32, who appeared on the show in 2016, was found hanged in June by her boyfriend, who later took his own life in similar circumstances.
In March this year another Love Island contestant, Mike Thalassitis, was found hanged in a north London park.
