Assisted dying bill: Special series #14 - MPs back assisted dying bill in historic vote

21 Jun 2025

This week, we reflect on a landmark moment in UK parliamentary history: the Terminally Ill Adults (End of Life) Bill has passed its Third Reading in the House of Commons, moving one step closer to legalising assisted dying in England and Wales. We are joined once again by former House of Commons Clerk Paul Evans to examine how this Private Member’s Bill navigated the political and procedural obstacles in its path and to explore what lies ahead in the House of Lords.

Please help us by completing our Listener Survey. It will only take a few minutes.

We start with the numbers: 605 MPs took part in the Third Reading vote, an exceptionally high turnout for a Private Member’s Bill, signalling the seriousness of the issue. With a majority of 23, the Bill now advances to the House of Lords, but not without questions over the opposition’s next moves and whether the unelected chamber will respect the will of the Commons, or obstruct the Bill’s path?

This historic moment wasn’t achieved by debate alone. It was the product of a quiet but coordinated effort to protect parliamentary time and avoid the procedural ambushes that often beset Private Members’ Bills. Other backbench sponsors of Private Members Bills temporarily stood aside to give the assisted dying bill a clear route through, critics refrained from procedural sabotage, and the Speaker and his deputies helped shape a timetable, ensuring MPs knew when decisions would be made.

Now the focus turns to the Lords, where the Bill may face its toughest challenges yet. Will Peers accept that the principle of assisted dying has been established by the elected House, and limit themselves to scrutiny and amendment of the details? Or could opponents attempt to delay or even derail the Bill entirely? We explore the possible scenarios and the constitutional, political, and procedural stakes in each case.

We also look at how the extensive scrutiny of the assisted dying Bill contrasts sharply with the swift and limited debate on abortion decriminalisation earlier this week – an issue settled via a backbench amendment to the Police and Crime Bill that was debated for just 45 minutes.

Finally, we consider what this might mean for the bigger picture. If this Bill is indeed the most far-reaching social reform since the 1967 Abortion Act, might it be the harbinger of a new wave of legislation promoting further social change?

Ruth Fox: Welcome to Parliament Matters, the podcast about the institution at the heart of our democracy Parliament itself. I'm Ruth Fox.

Mark D'Arcy: And I'm Mark D'Arcy, and welcome to the latest in our special series of podcasts following the progress of the Terminally Ill Adults (End of Life) Bill, the Bill that would enable assisted dying in England and Wales. And Ruth, the big news today is that the Bill has now cleared its final stage in the House of Commons. Its Third Reading. It won by a slightly reduced majority, but it won all the same.

Ruth Fox: Yeah, so we had 314 MPs voted for the Bill and 291 against, so it came through with a majority, as you say, a bit a bit of a reduced majority, [00:01:00] 23, compared to that Second Reading vote, uh, back last year, which was 55. Interestingly, same number of MPs voting: 605 plus four tellers for the vote. That is a very big turnout. I mean, we've set that in context with 650 MPs in the House. So where were the other 45? Well, there were some ministers abroad, David Lammy, for example, away, dealing with the Iranian situation. Take out the Speakers, the Deputy Speakers, the MPs who chair the Public Bill Committee stages, who don't vote at Third Reading.

Mark D'Arcy: The Sinn Feiners who, don't take their seats. The SNP who wouldn't vote on an England only, or England or Wales only issue. And actually you've got almost the theoretical maximum number of MPs who could have voted in this division, voting in this division, including such luminaries, of course, as the Prime Minister himself, Sir Keir Starmer

Ruth Fox: Suggestions that he might not be able to because of the international situation, but he was there in the voting lobbies. We understand

Mark D'Arcy: He took time out from stopping the slide to World War III.

Ruth Fox: [00:02:00] So it will now go to the House of Lords for, for further consideration. But it does mean that it will go into law, I suspect, I think it may struggle to get through quickly in the House of Lords. I think it'll be an extended process, but given that there is a solid majority for it in the Commons, I think that it'll go through the House of Lords. The question is how much it will be amended and how much time it will take up being sent back to the Commons.

For them to, to be asked to think again about some of the, the detail of the Bill perhaps. But if it gets through the House of Lords, then it will be probably the most significant piece of social legislation of my lifetime.

Blog / What role does Parliament play in the Spending Review?

The UK Spending Review outlines how Government funds will be allocated over several years. Unlike the Budget, which raises revenue, the Review decides how it is spent. But how is it approved? What role does Parliament play if it doesn’t vote on the Review itself? This blog explores how the Spending Review works, how it differs from the Budget, and how Parliament holds the Government to account through the Estimates process.

Submissions / Evidence to the House of Commons Modernisation Committee: Priorities and strategic aims

In response to the Modernisation Committee's call for views on 17 October 2024, we submitted evidence outlining key areas we believe the Committee should prioritise.
