Labour support for legalising assisted dying appears to be falling as more MPs publicly question the law change.

The Commons will next week debate changes to the plan to allow terminally ill people with less than six months to live to end their own lives, ahead of a crunch vote later this month.

But fresh concerns have been raised about the The Terminally Ill Adults (End of Life) Bill that is being led through Parliament by backbencher Kim Leadbeater.

Opponents have complained the Bill does not have enough protections and has been rushed through, with the criticism coming days after two royal medical colleges voiced their doubts on the legislation in its current form.

And now even supporters of the principle of legalising assisted dying are questioning the process.
