LONDON, England (CNN) -- A British TV channel was scheduled to air a controversial documentary Wednesday night showing a terminally ill man committing assisted suicide. Craig Ewert dictates a letter to his children before leaving for his assisted suicide in Switzerland. The film follows retired university professor Craig Ewert during the last four days of his life in 2006, when he visited a Swiss clinic with his wife, Mary, in order to die. The 59-year-old suffered from motor neurone disease (MND), which deprived him of the use of his arms and legs and caused him to be on a ventilator, Mary Ewert told The Independent.
