Senators in Chile passed a long-awaited bill Wednesday authorizing same-sex marriage, in what LGBT campaigners hope will be the penultimate step to its final approval. Chile, which legalized same-sex civil unions in 2015, has been waiting on this bill since 2017, when it was sent to congress by then-President Michelle Bachelet. In a surprise move, her conservative successor, Sebastian Pinera, announced last year he would seek the bill’s urgent passage through parliament, and on Wednesday, the senate approved the bill by 28 votes to 14. The bill will now be sent to the Chamber of Deputies, the second house of congress, for the final okay.
