A bill to legalise assisted suicide in Scotland has passed its first stage.

Members of the Scottish Parliament (MSPs) voted by 70 to 56 to endorse the general principles of the bill in a wider margin than had been anticipated.

Opponents of the bill say a law change would send a message “that some lives aren’t worth living” and vowed to continue to fight against the plans.

It is still far from certain that the bill will become law. The legislation is opposed by several of Holyrood’s most influential figures and just seven MSPs need to change sides to defeat it.

During an “impassioned” five-hour debate, several MSPs made clear that they voted in favour despite having reservations over some of the details. They have indicated that they may withdraw their support if these concerns are not now addressed before a final vote.
