The Terminally Ill Adults (End of Life) Bill was approved by MPs in June 2025 but has since stalled in the Lords with over 1,200 amendments.
Labour MP Kim Leadbeater, who introduced the bill in the Commons, told BBC Breakfast: ‘When the Bill went to the Lords I was already clear that I welcomed the scrutiny, I welcomed any refinements that the Lords might want to make to the legislation.
‘That is their job but it isn't their job to table so many amendments, many of which were inappropriate and some of which were quite cruel, that stopped the Bill from reaching the next stage.
‘It's a sad day and those that need to remain at the heart of this are terminally ill people.'
Members of the Scottish Parliament voted against an assisted dying bill in March.
Supporters have said they are confident the legislation will return in the next session of Parliament from 13 May.
