Peers are debating former Labour Lord Chancellor Lord Falconer's assisted dying bill.
The Bill proposes allowing doctors to give a lethal dose to terminally ill patients judged to have less than six months to live.
A survey conducted for ITV's Tonight programme found 70% would support allowing assisted dying under the framework outlined by the Assisted Dying Bill.
Church of England members remain against any change in the laws surrounding assisted suicide, the Bishop of Carlisle told ITV News, after the former Archbishop of Canterbury Lord Carey dropped his long-standing opposition.
Right Reverend James Newcome, who is also the lead bishop for the Church of England on healthcare, said: "We reckon that the compassion that Lord Carey talks about, which we share absolutely, needs to be extended to them [most vulnerable people]".
Ahead of tomorrow's Lords debate on assisted peers, Tonight speaks to those arguing passionately for and against the Bill.
Chris Woodhead, the ex-Ofsted chief who suffers from motor neurone disease, has made an emotional call for assisted dying to be legalised.
Lord Falconer insists his Bill will provide clarity to fix Britain's "broken" laws around assisted death whilst protecting the vulnerable.
