A man depicted in a poster for the upcoming referendum has spoken about how it feels to unknowingly be the face of the No campaign.

Irish sports stars have lined out in favour of the marriage equality yes campaign, saying a change in the law will tell young fans: “It’s OK to be who you are.”

Marriage equality campaigners will have to wait “a decade or more” for another “opportunity” to introduce the legal change if the electorate fails to vote yes in next month’s referendum.
