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.
A group of peers opposed to moves to legalise assisted dying legislation have pledged not to vote against a bill in the House of Lords on Friday. They believe further parliamentary scrutiny will expose the law's flaws.
The legislation tabled by Lord Falconer, proposes allowing doctors to prescribe a lethal dose to terminally ill patients with less than six months to live.

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.
