Does he not understand what endonyms and exonyms are? “Falkland Islands” is the English name, Islas Malvinas is the Spanish name. Legally, the Falkland Islanders are a British overseas territory administered by the UK but claimed by Argentina (hence the Falklands War of 1982, which lasted just 10 weeks). Demographically, English is the first language of the majority of Falkland Islanders as the majority are of British descent (with about 10%, mostly immigrants, speaking Spanish natively, with all students learning Spanish in school).
