Deputy Prime Minister Nick Clegg said in a video presentation to supporters of gay marriage that civil institutions in Britain support couples in love regardless of their orientation.
"All couples should be able to make that commitment to one another, regardless of who they love," Clegg said in the online video for the Out4Marriage campaign.
Support for same-sex marriages is not universal in Britain, The Daily Telegraph said Wednesday. Proposals to change the law on marriage have run into opposition from the Church of England and Roman Catholic Church as well as conservatives in Parliament.
But Clegg was not deterred.
"We brought forward our proposals -- they have provoked a heated debate," he said in the video. "But these are proposals about when and how to open up civil marriage to gay and lesbian couples. It's not a matter of 'if' anymore."
