Malta, a predominantly Catholic nation, is set to vote for same-sex marriage.
However, the Catholic Church is objecting the motion.
When the Labour government won its second term last month, it promised to introduce the legislation as its first law, which the opposition party equally supports.
However, many are questioning whether the law will pass unanimously or if there will be any opposing votes.
The Bill, which will be voted on later today, is piloted by Malta's Equality Minister Helena Dalli, as she wants to "modernise the institution of marriage."
This will be the latest turn-around in the country, since divorce wasn't legalised until 2011.
Adoption among gay and lesbian men and women in civil unions was only introduced in 2014.
