Forty-one years after the Falklands war, the UK has suffered a diplomatic defeat over the archipelago as the EU appeared to endorse the Argentine name for the disputed territory, Islas Malvinas.
Brussels supported an Argentina-backed declaration referring to Islas Malvinas at a summit of EU leaders with Latin America and the Caribbean (Celac) leaders on Tuesday, which Buenos Aires called a “diplomatic triumph”.
Isn’t that just their name in Spanish? (And French I think, maybe others too)
Yes, that’s what I was going to say also.
I am Spanish and they were always called Malvinas for us.
This was a summit with Latin America and the Caribbean countries and I assume it is the same for them. The Falklands name sounds totally made up to us.
You can even see the Wikipedia articles in most Latin languages call them Malvinas:
