The SNP has been warned that it stands to lose party members of faith if it supports calls to legalise assisted suicide.
Councillor Chris McEleny told The National that backing assisted suicide was "simply not compatible to the faith based belief systems of many people in Scotland".
McEleny, a Catholic, continued that it would be wrong for the party to take positions on "profound matters of conscience such as euthanasia".
"Therefore to adopt a party policy position that is incongruous to the beliefs of many party voters would make continued membership of the party not compatible with their faith," he said.
His comments follow the call this week from Josh Aaron-Mennie, a member of the SNP's National Executive Committee, for a change to the law.
Aaron-Mennie plans to bring forward a motion on assisted suicide to the party's annual conference in October after watching his grandmother suffer at the end of her life.
He said the experience was "unbearable" and that she had been "denied dignity".
The Scottish Daily Record reports that End of Life Choices, a cross-party group of MSPs, is preparing for a third push in Holyrood to legalise assisted suicide.
