The polling was carried out by Opinium Research on behalf of Dignity in Dying, and canvassed the views of 4,000 people across Wales. 72% said they support the legalisation of assisted dying in Wales for terminally ill adults with mental capacity.
The polling also found:
- 76% said if assisted dying for terminally ill adults were to be a legal option in England, it should be a legal option in Wales as well
- If assisted dying were legal, three in five respondents (62%) believe it should be accessible as part of NHS Wales services while just 17% think it should be delivered through a separate, non-NHS service
- 68% think it would be unfair for assisted dying to be available through the NHS in England but only privately in Wales
- Significant support for assisted dying across the political spectrum, with clear majorities among voters of all parties. This includes those who plan to vote Green (85%), Plaid Cymru (78%), Welsh Labour (77%), Welsh Liberal Democrat (74%), Reform (70%), and Welsh Conservative (67%)

While the Senedd does not currently have the powers to legalise assisted dying in Wales, it has a key role to play: a Legislative Consent Motion will come forward if new proposals are introduced in Westminster in the next session, as decision making on and delivery of any assisted dying service will be extensively devolved to the Senedd and Welsh Government.
