LONDON (Reuters) - Britain\u2019s parliamentary media committee has launched an investigation into the treatment of participants in reality TV shows after a man died shortly after appearing on an ITV program. The Digital, Culture, Media and Sport Committee said it would investigate whether enough support is offered to participants both during and after filming, and whether there is a need for more regulatory oversight in the area. ITV, Britain\u2019s biggest commercial free-to-air broadcaster, said on Wednesday it had canceled the Jeremy Kylie talkshow after a participant died after appearing in an episode that was never broadcast. The committee noted two former contestants in a popular reality dating show had also later died. Reporting by Kate Holton; editing by Stephen AddisonOur Standards:The Thomson Reuters Trust Principles.
