Miss Purdy said recently: "I don't want to die. I'm extremely happy in my life, I love being married to my husband, I love my friends. But if I leave it too late and need his help, he faces 14 years in jail. And that's more frightening to me than going to Switzerland by myself and ending my life before I'm ready." Miss Purdy, of Bradford, West Yorks, was diagnosed with primary progressive MS in 1995 and is in a wheelchair.
