Imams in Glasgow have told all Muslims throughout Scotland not to vote for any local election candidate on 3 May who supports redefining marriage.
The news will trouble the leaders of major parties, all of whom have indicated their personal support for the plan.
A statement was issued yesterday by the Council of Glasgow Imams and it is being sent out to Muslims throughout Scotland.
The statement said: “We urge the Deputy First Minister Nicola Sturgeon to look very seriously at this fundamentally important issue and to re-consider the full implications of what she is proposing.
“We wish to inform both her and the First Minister Alex Salmond that we are deeply unhappy and vigorously opposed to the proposed legislation for same sex marriage.
It added: “We will be urging our community from the pulpit to make sure that any person they consider voting for does not favour the proposed legislation.”
