Former first minister Nicola Sturgeon will not back a proposal to bring in assisted dying in what she described as the "most difficult decision" of her career as an MSP.
A new law allowing terminally-ill people to take their own life, put forward by Liberal Democrat MSP Liam McArthur, will be voted on at the Scottish Parliament on 13 May.
Sturgeon said she would not support the legislation because of fears around the threat of coercion and the definition of a terminal illness being too broad.
The ex-SNP leader will join her successors Humza Yousaf and John Swinney, along with Deputy First Minister Kate Forbes and Scottish Labour leader Anas Sarwar, in opposing the legislation.
