Swiss Federal Chancellery, the request for a referendum on same-sex marriage gathered more than 61,000 valid signatures.The SVP has stated that it is "intolerable to want to place marriage on an equal footing with any form of cohabitation".The date of the vote has not yet been set, as Swiss citizens are used to voting three or four times a year on a variety of issues under their system of direct democracy.Switzerland adopted its bill on same-sex marriage in 2020 after a long parliamentary battle and fierce support from the Green Liberals party.Previously, same-sex couples could enter into "registered partnerships" that did not give them the same rights as marriage.But the new legislation allowed them to wed and have access to sperm.
