ITV Studios has been accused of "corporate failure of responsibility" following the death of a man who is suspected to have killed himself after appearing on The Jeremy Kyle Show.
MPs accused the production company of failing to provide a "safe space" to participants after viewing behind the scene footage handed to them by a whistleblower.
The Digital, Culture, Media and Sport Committee said the video raised concerns about guests' welfare and showed that filming often continued backstage and in the guests' dressing rooms, Sky News reports.
The footage showed that "humiliation, denigration and provocation" had become "normalised", according to the committee.
Steve Dymond, 63, died roughly a week after taking part in the reality programme where he failed a lie-detector test.
The recording of Steve took place on May 2, but was never aired after the daytime show was axed the following day of his death on May 10.
A family barrister told a pre-inquest review into his death earlier this month that Steve "did not get the appropriate support from the aftercare team".
Digital, Culture, Media and Sport Committee chairman Damian Collins said: "It is clear that once the cameras started rolling on The Jeremy Kyle Show there was no safe space for anyone in a highly distressed state, verified by the behind-the-scenes footage passed to the committee by a whistleblower.
"We've seen one contributor who was extremely upset take refuge backstage only to have a camera thrust in his face to capture him holding his head in his hands.
"We've also seen how Jeremy Kyle would use provocative and sometimes abusive language towards participants in the show, and that this could be edited out of the broadcasted show.
"The overriding concern of the Reality TV inquiry has been to examine the production companies' duty of care towards people who take part, often at an extremely vulnerable point in their lives.
"We've shown this recording to expert advisers who are deeply concerned at ITV's apparent failure to prioritise the welfare of participants over the demands of the show, exploiting their vulnerability for the purpose of entertainment.
"What we've seen demonstrates a failure on the part of ITV studios in its responsibility towards contributors and makes a mockery of the 'aftercare' it has claimed to provide."
A spokesperson for ITV said: "ITV cancelled The Jeremy Kyle Show in May. We have since made clear that we will not bring back the Jeremy Kyle Show, or any other show resembling its format.
"The physical and mental health of everyone we work with is our highest priority and ITV is committed to working across the industry - including with other broadcasters, PACT and our regulator Ofcom - to share best practice and continue to strengthen and evolve our Duty of Care processes.
"The participation of the public in television programmes has been right at the heart of TV since it began.
"We believe that these shows are all the better for the talent, energy and diversity of the members of the public who take part in them and we are committed to continuing to ensure that their welfare is also at the heart of what we do."
They added: "We cannot comment on accusations based on footage the Select Committee has not shared with ITV."
