Terminally ill people with depression could qualify for assisted suicide

Terminally ill people who are depressed could receive assisted suicide under the criteria in the Leadbeater assisted suicide Bill after proposals to tighten legislation were rejected.

Last month, the parliamentary committee scrutinising the assisted suicide Bill voted against amendments that sought to prevent terminally ill people with mental illnesses from accessing assisted suicide if their illnesses cloud their judgement.

Whilst the Terminally Ill Adults (End of Life) Bill applies to mentally competent adults who are thought to have fewer than six months to live, the legislation defines “mental capacity” in the terms given under the Mental Capacity Act 2005 (MCA), which states “a person must be assumed to have capacity unless it is established that he lacks capacity”.

MCA “not sufficient” according to Royal College of Psychiatrists 

In written evidence sent to the Committee, the Royal College of Psychiatrists (RCP) explain why the MCA   is “not sufficient” for people making such an important decision, underlining the difficulties people with both mental and physical illnesses have in decision-making. 

The RCP said “Decisions can be particularly complex for people with a physical terminal illness and mental disorder. There will be those who have significant histories of mental disorder prior to the physical terminal illness, and others who have mental disorder primarily in the context of their terminal physical illness. Hopelessness is a common symptom of depression and can affect a person’s ability to weigh information in the balance; anxiety can amplify fears of future suffering”.

The RCP warned that someone with a physical and mental illness “would not necessarily be deemed ineligible”. The RCP gave an example of a person with terminal cancer and clinical depression “which is influencing their wish to die”. However, under the Bill, this person may “be determined in accordance with the MCA as having capacity to decide to end their own life and therefore eligible for [assisted suicide]. While they may be capacitous, they might feel differently at a future time if provided with appropriate interventions and support to treat a co-occurring mental disorder”.

A similar point was also made during the Committee’s meeting at the end of January. Dr Annabel Price, representing the Royal College of Psychiatrists, related her experience of how people who want to die often change their minds when they get adequate pain relief. She said that “Unresolved physical symptoms make people want to die, and when that pain is better, people no longer feel that way”, reminding the Committee that even if someone decides to have an assisted suicide, they can change their minds when adequate support is provided. She added that depression is “common” near the end of life. However, if depression is treated, there is often a “significant change” in a wish to hasten death.

Proposals to tighten legislation rejected

Last month, an amendment by Lib Dem MP Sarah Olney, which was written in response to these concerns from the RCP and MPs, was voted down by the Committee by 15 votes to 8. It proposed using the word “capacity” rather than “ability” in the Bill. This would enable doctors to effectively assess a person’s eligibility for an assisted suicide. She said “My amendment… proposes that we should assess people’s ability to make the decision and not just their capacity”, adding that “all reference to mental capacity is assumed to refer to the Mental Capacity Act 2005, but I do not believe that that is sufficient for the purposes of the Bill”.

“When people are thinking about whether assisted [suicide] is an appropriate decision for them, I do not think that it is safe for them to be judged merely on the basis of their capacity”. 

Olney argued that “the Mental Capacity Act was not drafted in anticipation of it ever being used for this kind of scenario [assisted suicide]” and “is unsuitable for this purpose”. 

She said “Under the Mental Capacity Act, someone must be completely unable “to understand the information relevant to the decision…to retain that information…to use or weigh that information as part of the process of the making the decision, or…to communicate his decision”.

“If they are only partially able to do so, they will still be considered to have capacity under the Mental Capacity Act, so it is not a safeguard to protect a terminally ill person who happens to be suicidal due to depression”. 

However, Lewis Atkinson MP, one of the 15 Committee members who rejected the proposed safeguard for people with mental disorders, claimed “We should not be preventing anyone from accessing an option merely because of a mild element of depression”. 

Mental Capacity Act not suitable for assisted suicide 

Other MPs shared Olney’s concerns that the Mental Capacity Act is not suitable for assisted suicide. Daniel Francis MP pointed out that the Mental Capacity Act was not written for the purpose of assessing capacity for assisted suicide, but “to enable people to carry out day-to-day scenarios, such as buying a coffee or doing their banking, so that they are not challenged in every transaction in their life. It is therefore a very low bar to be deemed to have capacity”.

Francis also questioned the effectiveness of doctors in assessing mental capacity by referring to his own “lived experience” of looking after his “learning-disabled child”. He said he and his wife received phone calls “all the time” from doctors who wish to speak to his daughter, “despite their having read the notes saying that she is an 11-year-old with 12 words and a severe sight impairment”.

Francis said “I therefore query…how well some aspects of the Mental Capacity Act are currently being carried out”. Sean Woodcock MP said “we heard from three sets of psychiatrists who all cast doubt on the suitability of the Mental Capacity Act for decisions such as assisted [suicide]”. 
Danny Kruger MP reminded MPs that Dignity in Dying (formerly Voluntary Euthanasia Society) was delighted with the Mental Capacity Act as they recognised it would help their objectives to make assisted suicide legal.

Spokesperson for Right To Life UK, Catherine Robinson, said “To legalise assisted suicide would present an acute threat to vulnerable people, especially terminally ill people who are also suffering from mental illness. The last thing vulnerable people need is help to take their own lives, yet this is what is being proposed in Leadbeater’s dangerous Bill”. 

“Every suicide, without exception, is an utter tragedy and the 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?
