In December 2016, in his first press conference following taking office, Prime Minister Bill English announced he would vote in favour of same-sex marriage if another vote were to be held. He said "I'd probably vote differently now on the gay marriage issue. I don't think that gay marriage is a threat to anyone else's marriage." English voted against the Civil Union Act 2004 and the Marriage (Definition of Marriage) Amendment Act 2013, and in favour of the Marriage (Gender Clarification) Amendment Bill 2005.<sup>[21][22]
