Scotland is racing to catch up with England and Wales to give gay couples full equality under the law.
The devolved government are expected to finally outline their proposals to legalize same-sex marriage next week.
Going one step further than England and Wales, they are also expected to allow straight couples to enter civil partnerships.
Civil partnerships were first made legal in 2005, giving gay couples the ability to register their unions. They were given similar, but not all, the same legal recognition as married heterosexuals.
