TV presenters Richard Madeley and Judy Finnigan have said they have given each other "a pledge" to help end their lives if they become seriously ill.
The pair said the recent death of Mr Madeley's mother had got them thinking about the subject.
Mr Madeley told the Daily Telegraph he would not be put off by the prospect of being prosecuted, adding: "I'd do what was right for my wife, and I'd take the consequences. That is your job, that is your responsibility as a partner."
Mrs Finnigan agreed, saying: "I'd do the same: stuff it all. We've made ourselves give each other a pledge along those lines."
