Cuba has voted to legalise same-sex marriage in a national referendum.
About two-thirds of the population voted to approve reforms in a new Family Code, which will also allow surrogate pregnancies and give gay couples the right to adopt children.
It marks a big moment for Cuba, which saw gay people persecuted and sent to work camps in the 1960s and 70s.
However, there was significant opposition to the reforms among religious groups and conservatives.
The referendum on Sunday was for a new Family Code – a 100-page document which went through more than two dozen drafts and hours of debate in community-level meetings.
Cuba’s government had backed the law change and ran a nationwide campaign urging people to approve it.
Speaking as he voted on Sunday, the country’s President, Miguel Díaz-Canel, said he expected most of the population would vote yes and that the new code reflected the diversity of people, families and beliefs.
On Monday, preliminary results indicated an “irreversible trend”, with 66% of votes counted so far in favour of the reform, electoral council president Alina Balseiro said on state television, according to AFP news agency. The law required 50% of voters’ approval to be adopted.
The reforms were the culmination of efforts by gay rights activists in Cuba.
Official attitudes towards homosexuality on the Communist-run island have changed over the past decades, partly thanks to the efforts of former leader Raúl Castro’s daughter Mariela.
