Craig Ewert explains his decision in a clip from the Sky Real Lives programme
The makers of a documentary on assisted suicide have defended their decision to film a man at the moment of his death.
Motor neurone disease patient Craig Ewert, 59, from Harrogate, North Yorkshire, died in Switzerland, having been helped by the charity Dignitas.
Sky Television said its film gave an "educated insight into the decisions some people have to make".
However, campaign group Care Not Killing said the show was a "cynical attempt to boost television ratings".
Prime Minister Gordon Brown told the Commons he was personally opposed to assisted suicide.
Speaking at Prime Minister's Questions, he said: "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."
American father-of-two Mr Ewert died in September 2006 after drinking a mixture of sedatives and using his teeth to turn off his ventilator.
The former academic allowed his death to be filmed for a documentary, Right to Die?, made by Oscar-winning director John Zaritsky, which was shown on Sky Real Lives on Wednesday night.
Barbara Gibbon, Head of Sky Real Lives, said: "This is an issue that more and more people are confronting and this documentary is an informative, articulate and educated insight into the decisions some people have to make.
"I think it's important that TV broadcasters can stimulate debate about this issue through powerful, individual and engaging stories and give this subject a wider airing."
Dr Peter Saunders, director of the campaign group Care Not Killing, said the show was a "cynical attempt to boost television ratings".
He said: "The danger is that we start to believe in a story that there is such a thing as a life not worth living."
