Former high court judge calls for extension of assisted suicide to people without terminal illness

Campaigners are calling for the assisted suicide Bill to be expanded for people without terminal illnesses.

Under Kim Leadbeater’s Terminally Ill Adults (End of Life) Bill, only those thought to have six months or less to live are eligible to apply for assistance in suicide from the state, but former high court judge Sir Nicholas Mostyn, who has Parkinson’s disease and runs a podcast about the condition called Movers and Shakers, has expressed his wish to see the scope of the Bill widened to apply to people who are not terminally ill.

Mostyn, who said in the build-up to the vote that the “Bill is no f***ing use to [people with Parkinson’s] at all”, wants to see the scope of the Bill widened because the suffering experienced by Parkinson’s patients is “intolerable”. Speaking to MPs on the assisted suicide Committee, he said “You should get permission to have an assisted death if you are suffering intolerably within five months of death or seven months of death”. 

“It’s been suggested I want to expand the definition of terminal illness. I don’t want to expand it. I want to redefine it so that it is more appropriately focused” he said.

The Leadbeater Bill “is not ever going to provide an assisted death for me” he added.

Mostyn the latest to call for expansion of assisted suicide criteria

Mostyn is the latest person to call for the scope of Kim Leadbeater’s assisted suicide Bill to be widened to apply to those who are not terminally ill. When Leadbeater’s Bill was announced in October 2024, assisted suicide campaign group My Death, My Decision immediately complained that the Bill would “exclude people who are suffering unbearably but are not necessarily terminally ill”. Former NHS England Medical Director Dr Graham Winyard also called for Leadbeater’s Bill to include “both the terminally ill and the incurably suffering”. Winyard complained that less than half of UK residents who ended their lives by assisted suicide in Switzerland in recent years would have been eligible for assisted suicide under Leadbeater’s Bill.

Mostyn said it would not be possible to challenge the Leadbeater Bill on legal grounds and include people with neurodegenerative diseases if it became law. However, legal experts have shared concerns that the law could well be expanded. Barrister James Strachan KC explained that if assisted suicide were permitted, Article 14 of the ECHR, which protects against discrimination, could be engaged leading to a “slippery slope” of ever-increasing expansion.

Dr Philip Murray, Assistant Professor in Law at Robinson College, Cambridge University, also pointed to the potential use of Article 14, saying “If it’s possible to lift the ban for terminally ill people, why not those suffering from non-terminal disabilities or people experiencing chronic mental illness? Article 14 of the Convention prevents states from discriminating on grounds of disability and illness”.

Dr Murray told The Telegraph “No one supporting the Leadbeater Bill can claim with certainty that assisted suicide won’t expand in the future”.

“There are no people speaking against the operations of assisted dying laws internationally”

Dr Murray’s concerns about expansion are backed by statistics from jurisdictions where the law has been amended to include different groups. In 2021, the Canadian Parliament repealed the requirement that the natural death of those applying for euthanasia or assisted suicide be “reasonably foreseeable”. This took place only five years after the original legislation allowing euthanasia and assisted suicide was passed in 2016. Legislation was introduced in February 2024 so that euthanasia and assisted suicide would become legal on the grounds of mental health alone in March 2027. In 2023, The Netherlands widened its regulations allowing euthanasia for children of all ages.

Spokesperson for Right To Life UK, Catherine Robinson, said “As the disastrous programmes in Canada and the Netherlands have shown, the risk that assisted dying legislation will expand is all too apparent”.

“We would be naive to believe that the same could not happen in the UK if Leadbeater’s legislation becomes law. Her dangerous Bill should be scrapped immediately”.

Help stop three major anti-life threats.

Help build on the momentum from the defeat of the assisted suicide Bill and make this victory last.

Dear reader,

Thanks to the hard work and dedication of people like you across the UK, after a two-year battle, MPs voted by 286 to 270 to reject the Edwards assisted suicide Bill.

This followed the defeat of the McArthur assisted suicide Bill in Scotland by 69 to 57 in March this year.

Many commentators thought both Bills would become law.

If that had happened, this would have led to the deaths of many thousands of vulnerable people over the coming decades.

Because supporters like you acted, those Bills were stopped.

Because of you, many vulnerable lives have been saved.

A prominent pollster described the campaign against these major attempts to introduce assisted suicide, which brought together people from all walks of life across the UK, as one of the “most successful 21st Century UK social issue campaigns”. You helped make that possible.

WHY WE MUST NOT STOP HERE

What we have achieved together is extraordinary. But we must not rest on our laurels.

Dignity in Dying, a multi-million-pound pressure group, has made clear that it will keep campaigning to legalise assisted suicide. 

We cannot wait until another Bill is brought forward. We need to keep pressing for better care and strengthen the case against legalisation now.

WHAT COMES NEXT

The next phase of our Support Not Suicide campaign will operate across Parliament, media, online and in grassroots communities in every constituency across the United Kingdom.

Our focus now is to build on that momentum from the defeat of these assisted suicide Bills and make these victories last.

We want to build a United Kingdom where assisted suicide is seen as unnecessary – and where legalising it is seen as unthinkable.

The first part of that work is a sustained push for universal access to high-quality palliative, hospice and social care. No one should feel driven towards assisted suicide because they cannot get the care and support they need. 

We have already asked supporters to contact their MPs about improving care. With your help, we will keep that pressure on in every constituency, brief MPs and Peers on gaps in care, and make the case for better provision in the media.

The second part is building on these wins to ensure more MPs and more of the wider public understand the dangers of legalising assisted suicide. We will put evidence of those risks before MPs and Peers. We will work with mainstream journalists to bring the voices of people directly affected, doctors and other experts into the national conversation, and produce clear videos and articles that supporters can share online and in their communities.

Our network of 250,000 supporters covers every constituency in the UK. Thanks to people like you sharing our content, our posts and videos have been viewed more than 100 million times online in the last year. 

We want to utilise that massive reach for this next phase of the campaign.

WE CAN ONLY DO THIS WITH YOUR HELP

The two-year fight to stop these Bills drew heavily on our limited resources.

To replenish those resources and fund the next phase of the Support Not Suicide campaign, we aim to raise at least £199,250 by midnight this Sunday (4 October 2026).

We are, therefore, appealing to you to please give as generously as you can today.

Every donation, large or small, will make a crucial difference in protecting vulnerable lives. Plus, if you are a UK taxpayer, £1 becomes £1.25 with Gift Aid at no extra cost to you.

Will you donate now to help make these victories last and protect vulnerable lives?
