Following a June 2018 Supreme Court ruling that opened the institution to heterosexual couples, straight men and women have begun entering into civil partnerships in the United Kingdom.
Civil partnerships in the U.K. offer a similar legal arrangement to that of marriage. It had previously been available only to same-sex couples as an alternative to marriage. Gay marriage has been legal in the United Kingdom for more than five years.
One recently partnered couple told news media they opted for the arrangement because, as they put it, marriage is "patriarchal" and "sexist." The British government estimates that around 84,000 heterosexual couples will enter into partnerships this year.
