The controversial assisted dying bill is returning to the House of Commons, with MPs preparing for another major vote on whether terminally ill adults in England and Wales should be allowed to seek medical assistance to end their lives.

The Terminally Ill Adults (End of Life) Bill is expected to face a closely contested free vote, meaning MPs can vote according to their personal views rather than being bound by party instructions. The issue has divided politicians and campaigners across Parliament.

Supporters argue that the legislation would give terminally ill, mentally competent adults greater choice and control at the end of life, subject to proposed safeguards. Opponents have raised concerns about vulnerable people, pressure on disabled people and whether existing palliative care would be sufficient.

The bill previously passed the Commons in the previous parliamentary session but failed to complete its passage through the House of Lords before Parliament was prorogued. The renewed legislation has therefore reopened one of Westminster’s most sensitive debates.

The vote could become an important test of Andy Burnham's government and parliamentary opinion, while its outcome may determine whether assisted-dying legislation moves closer to becoming law.
