UK Prime Minister Gordon Brown declared his stout opposition to assisted death while the Sky TV is planning to screen footage of an assisted death in Switzerland.
The popular channel is to broadcast the last moments of Craig Ewert, 59, a father-of-two from Harrogate, as he is helped to take his life at the Dignitas euthanasia clinic.
At Prime Minister's Question Time, Mr Brown made clear his own opposition to assisted suicide, saying: "I believe that it is necessary to ensure that there is never a case in this country where a sick or elderly person feels under pressure to agree to an assisted death or somehow feels it is the expected thing to do.
"That is why I have always opposed legislation for assisted deaths.'"
The Prime Minister was responding to a question from Mr Ewert's MP Phil Willis (Harrogate and Knaresborough) who asked whether he thought the broadcast was "in the public interest or is it simply distasteful voyeurism?"
The Prime Minister went on: "I think it is very important that these issues are dealt with sensitively and without sensationalism and I hope broadcasters remember that they have a wider responsibility to the general public.
"Of course, it will be a matter for the television watchdogs when the broadcast is shown."
Earlier, at a regular Westminster briefing, the Prime Minister's Official Spokesman suggested that Ofcom, the broadcasting watchdog, would now consider whether the contents of the documentary abided by the Broadcasting Code.
