Jeremy Kyle has turned down a request to appear before MPs investigating reality TV.
ITV axed The Jeremy Kyle Show - which was filmed in Salford - in May, following the death of participant Steve Dymond.
The Digital, Culture, Media and Sport (DCMS) Committee then launched an inquiry into reality TV.
Senior executives involved in the show will appear in front of MPs on 25 June, but the star's representatives told the committee he would not give evidence.
The committee's chairman Damian Collins said: "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."
