A June 2018 YouGov opinion poll found that 80% of British people supported the introduction of same-sex marriage in Northern Ireland, with that number decreasing among Northern Irish respondents. 70% of Conservative voters, 89% of Labour voters and 90% of Liberal Democrat voters were in favour of its introduction. Among "Remain" voters, 90% supported same-sex marriage in Northern Ireland, whereas "Leave" voters supported it at 68% (this was at a time when in the aftermath of the 2016 EU referendum the issue of Brexit dominated British politics).
