TV regulator Ofcom has received around 100 complaints about daytime show This Morning after presenter Phillip Schofield confronted David Cameron with a list of alleged paedophiles, and is considering whether to launch an investigation.
Schofield handed the Prime Minister a list of names - understood to be Conservative Party figures - during the live show on Thursday, put together from internet rumours.
The "outrageous stunt" was widely criticised by politicians and the presenter was later forced to apologise after the list was briefly exposed on screen.
Rob Wilson, a Conservative MP, reported the ITV1 programme to Ofcom and urged it to investigate whether ITV breached its duty to give individuals a chance to respond before subjecting them to serious allegations on-screen.
The broadcasting regulator is understood to have had around 100 complaints and it will make a decision about whether it should look into the matter within 15 working days. A spokesman for Ofcom said: "We can confirm that we have received complaints about this issue, which we are assessing. No decision has been made at this stage to investigate."
After being handed the list, which Schofield had assembled after trawling the internet for three minutes, the Prime Minister warned that internet discussions of an alleged paedophile ring could degenerate into a "witch-hunt" against people who are gay.
Policing and criminal justice minister Damian Green said Schofield's actions were "tasteless and silly".
Speaking on BBC1's Question Time, he said: "What the Prime Minister was warning about is that if we just start plastering names all over the place, of people against whom there may be no evidence, it may well turn into a witch-hunt and clearly because of the attitudes towards gay people at the time, in the 80s, many of them are likely to be on it."
Schofield was absent from the latest edition of This Morning as he and co-host Holly Willoughby hand over presenting duties to Eamonn Holmes and his wife Ruth Langsford each Friday. But the programme team emphasised they were not pointing the finger at anyone in particular.
Langsford reiterated to viewers Schofield's point about a "misjudged camera angle" and she added: "The programme was not accusing anyone of anything."
