David Tennant’s father has come out in support of giving people at the end of their lives the right to die, calling for “assistance towards a peaceful death” for terminally ill patients like himself. The Very Reverend Sandy McDonald suffers from pulmonary fibrosis – a rare lung condition for which there is no cure. Speaking out about his condition, the 77-year old said: “I have pulmonary fibrosis. It just gets worse, there is no cure. I have had to address it and decide what to do. “I have an advance directive which says ‘do not resuscitate’. I do not want to be fed by something in my stomach. What I do want is the right to a peaceful end to my life.” McDonald, who was a Moderator of the General Assembly of the Church of Scotland, says he wants to change the conversation around the right to die, making the action sound less threatening: “I think we have the wrong slant, the wrong emphasis. The phrase - assisted suicide - has criminal overtones in the minds of many people. “We need to take seriously the provision of a peaceful end of life for all those who need and want it. Of course there would have to be safeguards and that should be discussed.” Tennant recently praised his father as a role model during his acceptance speech for the Special Recognition Award at the National Television Awards, telling the audience: “I would like to dedicate this to my dad. He's an inspiration and a role model. Thanks, Sandy."
