The United Kingdom has firmly stated its claim over the Falkland Islands, asserting that they are "definitely ours" after Argentinian players displayed a banner related to the sovereignty dispute following a World Cup match. The incident has drawn strong reactions from British politicians.

The Falkland Islands remain a subject of contention between Britain and Argentina, with a history of conflict over the territory. A war in 1982, initiated when Argentine forces landed on the islands to assert a territorial claim, resulted in significant casualties on both sides. British military personnel, islanders, and Argentine soldiers died during the 74-day conflict.

A spokesperson for the UK prime minister reiterated the nation's stance, stating that the principle of self-determination rests with the islanders and that the commitment to the Falklands is unwavering. The spokesperson suggested that any potential disciplinary action against the Argentinian players for displaying the banner would be a matter for FIFA, the international governing body for football. This sentiment was echoed by Business Secretary Peter Kyle, who called for FIFA to investigate.

In a 2013 referendum, the residents of the Falkland Islands voted overwhelmingly to remain a UK overseas territory. Out of 1,517 votes cast over two days, with a turnout exceeding 90%, 1,513 were in favor of remaining a UK territory, with only three votes against.

Political figures from various parties condemned the display. Liberal Democrat leader Sir Ed Davey called for the Argentinian players to be barred from the final, drawing a parallel to UEFA's one-game ban on Spanish players for chanting about Gibraltar during Euro 2024 celebrations. Conservative Party leader Kemi Badenoch stated unequivocally, "The Falkland Islands are British. The Conservatives will always defend them." Reform UK leader Nigel Farage expressed disgust at the players' actions and advocated for strengthening the Royal Navy.
