I’m aware that the name isn’t popular in Ireland, but I’m not aware of an alternative, never mind one that’d be widely understood.
I totally apologise. I knew that Éire (my preference) was kind of frowned-upon in English, and wanted to avoid confusion about the country vs. the island, but should have recalled that ‘Republic of Ireland’ is also a loaded term.
FWIW, my partner is Irish (by hastily acquired passport and genuine family links!) and that’s another of our Brexit escape routes.
