The predominantly Catholic country became the latest in the EU to legalize marriage for same-sex couples at the beginning of the year, joining Belgium, Denmark, Finland, France, the Netherlands, Portugal, Spain, Sweden, and the United Kingdom. Ireland may be next, as voters there prepare to take part in a referendum next Friday on whether to give gay and lesbian couples the right to wed.

Only one other serving head of government has ever married a same-sex partner. In 2010, Jóhanna Sigurðardóttir, then the prime minister of Iceland, married her longtime partner, Jónína Leósdóttir.
