Assisted dying debate: 'I knew he'd made up his mind'
On Friday, MPs will debate whether or not to legalise assisted dying.
It would enable any adult in England and Wales who is terminally ill to ask doctors for a lethal dose to end their life.
Those in favour argue it would enable patients to die with dignity and without pain but those against say it would set a dangerous precedent and is unnecessary.
Ed Thomas spoke exclusively to the family of Jeffrey Spector, who wanted a change in the law, and travelled to Switzerland to end his life.
