​Argentina broke a FIFA rule after unveiling a banner with a political statement following their World Cup semi-final win against England.Lautaro Martinez’s 93rd minute header broke English hearts as Lionel Scaloni’s men moved to within one game of becoming back-to-back champions, providing that they beat Spain in Sunday’s final.AdvertisementAdvertisementAdvertisementThe game between the two nations was played under the backdrop of an intense rivalry that has existed since 1986 and the war on the Falkland Islands.After the game, the Argentine players unveiled a banner which read ‘Los Malvinas son Argentinas’ (The Malvinas Islands (Falklands) belong to Argentina in English) but this broke a rule.Photo by Ian MacNicol/Getty ImagesFIFA rules state that “banners, flags, flyers, apparel and other paraphernalia that are of a political, offensive, and/or discriminatory nature” are prohibited from being brought into the stadium.In this case, the flag displayed by the Argentina players clearly falls foul of those rules and they could face punishment.AdvertisementAdvertisementAdvertisement649 Argentine soldiers and 255 British combatants died during a war on the Falklands in 1982 which has been under British occupation ever since after the majority of residents voted in favour of remaining with them.Argentina has long claimed it inherited the islands from Spain after its independence in 1816 and that Britain took control in 1833 through an illegal colonial act and only acknowledge the South Atlantic island as the Malvinas.Earlier on in the tournament, Iranian fans displayed a banner that is recognised as symbols of protest against the Tehran government, but faced no sort of punishment for doing so.
