Argentina display their controversial banner

FIFA has confirmed it will investigate the display of a political banner by the Argentina squad at the weekend.

The players unfurled a banner which said 'Las Malvinas Son Argentinas' (The Falklands are Argentine) before their match with Slovenia on Saturday night.

The team has paraded similar banners before, but with the World Cup about to start the incident has put the gesture under the spotlight.

FIFA, which does not allow political messages during matches, has confirmed to Sky Sports News it will review the incident which could lead to a punishment for Argentina.

Argentina invaded the Falkland Islands in 1982, but British forces forced their surrender after a short but bloody war.

Argentina lost 649 servicemen during the conflict, the UK 255. In a recent referendum on the Falklands on whether the islanders wanted to remain British, 1513 voted yes and just three voted no.

The sovereignty of the islands remains a big issue in Argentina, with the vast majority of the public wanting them back under Argentine control.
