Tory MP Damian Collins has said he thinks Jeremy Kyle should face jail for refusing to give evidence over his now-axed show.
After Mr Dymond's death, the Digital, Culture, Media and Sport (DCMS) Committee launched an inquiry into reality TV.
Last month, a committee meeting was held to investigate the daytime show and Jeremy was asked to give evidence but he refused to attend.
Instead, executive producer of The Jeremy Kyle Show, Tom McLennan and Director of Aftercare Graham Stanier and other ITV bosses were slammed for failing to establish the accuracy of lie detector tests.
Mr Collins has now said he wants more to be done if people refuse to attend hearings.
He told The Guardian: "I believe we need to formalise powers and have clear real-world sanctions for those that refuse to comply with a request to provide evidence.
"In the US, such behaviour is treated as a criminal offence, just as perjury in court would be. These committees have become a place where parliament can stand up for the interests of the people.
"I am strongly in favour of real-world sanctions for those who fail to comply with parliamentary committees."
Last month, Mr Collins said in a statement: "The Jeremy Kyle Show is an important programme we will be looking at as part of the inquiry into reality television.
"We have sent an invitation to Mr Kyle through his representatives and we have received word back from them that he has declined to appear in front of the committee on Tuesday next week."
I am strongly in favour of real-world sanctions for those who fail to comply with parliamentary committees.
Jeremy was left "devastated" in May when his daytime talk show was axed following Steve's tragic death.
His death came amid growing scrutiny over the duty of care reality TV shows have to participants following the deaths of Love Island contestants Sophie Gradon and Mike Thalassitis.
Jeremy said in a statement to The Sun at the time: "Myself and the production team I have worked with for the last 14 years are all utterly devastated by the recent events.
"Our thoughts and sympathies are with Steve's family and friends at this incredibly sad time."
