The country has recognised same-sex unions since 2015 but stops short of full marriage equality.

Kyriakos Mitsotakis, the Prime Minister of Greece, has promised to legalize same-sex marriage in a huge step forward for LGBTQ+ rights. “Same-sex marriage will happen at some point and it’s part of our strategy,” he said during an interview with Bloomberg Television in Athens on 4 July.

But in reality, as @strangerloop@beehaw.org pointed out, in recent elections 12.76% of the voters went with far right (3 parties, one of them directly supported by convicted criminal party with many Nazis in their line-up) whose views on the subjects are clearly against.

And, even though same-sex unions were recognized in 2015, when the relevant legislation was put into a vote, the party that is now in government (40.56% of the voters) voted against the same-sex unions (31 voted no / 18 voted yes / 27 were not present).

So, even though this sounds like good news and I hope it is actually true, it looks more like part of their communication strategy on the media rather than part of an actual agenda for the future.
