Three Argentine players unfurled a banner reading “Las Malvinas son Argentinas” after their team’s 2-1 semi-final victory over England at the 2026 FIFA World Cup in Atlanta on July 15. FIFA is now considering disciplinary action, and the UK government has publicly urged the governing body to investigate.

What happened in Atlanta

Following the final whistle, at least three Argentine players, Giovani Lo Celso, Lisandro Martínez, and Nicolás Otamendi, held up the banner referencing Argentina’s longstanding territorial claim over the Falkland Islands. The dispute dates back to 1982, when Britain and Argentina fought a brief but bloody war over the South Atlantic archipelago.

FIFA’s rules ban political, religious, or provocative messages from the field of play. The organization fined the Argentine Football Association £20,000 in 2014 after a similar banner appeared during a friendly match against Slovenia.

The UK government has responded by demanding a thorough FIFA investigation. FIFA has not yet announced specific sanctions, but options on the table could range from individual player fines and suspensions to penalties against the AFA itself.

The broader geopolitical angle

The Falklands dispute has simmered for over four decades. Argentina’s government has consistently maintained its claim to the islands, which it calls Las Malvinas. The UK has been equally firm in asserting British sovereignty, backed by the wishes of the islands’ residents.
