More than 100 peers are hoping to speak on Friday's debate about Lord Falconer's Assisted Dying Bill that seeks to give terminally-ill people control over the timing and manner of their death.
But disability campaigner and former Paralympian Tanni Grey-Thompson claimed the bill was a "chilling prospect for disabled people".
And in a personal film for BBC1's This Week, Baroness Grey-Thompson spoke about the reaction from some people to her disability, and how: "In their eyes, my life is not worth living."
