UK Labour MP Kim Leadbeater’s euthanasia bill is “the biggest threat we’ve faced since the Marris Bill in 2015. We defeated it then, and we can do so now, but we need a huge effort to lobby MPs. Over half of MPs are new to Parliament and have not voted on this issue before,” the Society for the Protection of Unborn Children says.

In 2015, Labour MP Rob Marris introduced the Assisted Dying Bill, also known as the Marris Bill, to the House of Commons. The bill aimed to legalise assisted dying for terminally ill patients with less than six months to live. It was the eleventh attempt in twelve years to legalise assisted suicide through British Parliaments.

Now, the Terminally Ill Adults (End of Life) Bill, introduced by Kim Leadbeater, MP for Spen Valley, on 16 October 2024 and published on 11 November, will be debated by the House of Commons on 29 November 2024. The Bill seeks to amend the Suicide Act 1961 to allow doctors to supply adults with a “terminal illness” with lethal drugs to end their own lives.
