Jeremy Kyle has refused to appear before MPs following the axing of his controversial talk show.
The Jeremy Kyle Show was cancelled last month after Steve Dymond died in a suspected suicide shortly after appearing on the ITV programme.
Presenter Mr Kyle was asked to appear before a House of Commons committee next week, as part of an inquiry into reality TV. But Mr Kyle has turned the invite down.
Digital, culture, media and sport committee chairman Damian Collins said on Tuesday: "The Jeremy Kyle Show is an important programme we will be looking at as part of the inquiry into reality television.
"We believe that Jeremy Kyle himself should be an important witness to that, as the show is based around him as the lead presenter of it.
"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.”
But Mr Collins promised to pursue the matter and haul Mr Kyle before MPs.
He added: “We believe that Mr Kyle is an important witness to the committee in its work and we will be pursuing this matter with Mr Kyle's representatives to see if we can find a date when he will appear or to understand fully the reasons why he is not able to appear.
"We will make a further statement once those discussions have concluded."
The inquiry will invite a range of former participants and programme-makers to give evidence over the coming months.
Mr Dymond, 63, died around a week after reportedly failing a love-cheat lie-detector test on Mr Kyle's confrontational daytime programme.
The construction worker was found in his room in Portsmouth on May 9 after splitting from on-off fiancee Jane Callaghan.
