I'll explain it for you then. The passport says EU on the front so that it enables the holder, upon establishment of their details, unhindered travel throughout the EU. The EU cover of the passport does not define the nationality of the holder. The details on the data page define this. Ergo, 28 countries have the same cover passport but with 28 different nationality statuses. This is relevant for defining the nationality status of the holder should they wish to travel elsewhere in the world. I do not understand the fact that you stated that Irish nationals have EU passports. So do 27 other countries. What is your point Pete, or don't you really understand what you're talking about?
Mad that someone who comes across as intelligent thinks its an EU issued passport simply because the cover has an EU logo on it.
Everything else in the passport relates to Ireland only. It is written in part in its native language (including the cover) and says it's issued by the Irish government. Given that the staff that work at the passport office work for and are paid by the Irish government and not governed by the EU tells it all.
But sure its an EU issued passport haha!!
Nothing but another Pete falsehood like those "laws" the EU insist on making us live by.
