Argentina’s President Javier Milei in front of the United Nations General Assembly

Argentina threatens legal action against UK over Falkland oil exploration


Argentina’s President Javier Milei has set a two‑week deadline for Britain to scrap the Sea Lion oilfield project, a joint venture between Israel’s Navitas Petroleum and Britain’s Rockhopper Exploration, or face international arbitration.


The Sea Lion field sits about 130 km north of the Falkland Islands and is said to hold roughly 1.7 billion barrels of oil. Both companies insist the licences are valid and have been granted by the UK government, while Milei accuses the UK of “illegal plundering” and threatens a legal challenge through the International Tribunal for the Law of the Sea.


The friction comes on the heels of a speech Milei gave at the United Nations where he slammed the organisation as “useless” and called the Falklands a “clear and present danger.” UK Defence Secretary Wes Streeting has counter‑ed, arguing that Argentina lacks the means to seize the islands by force.


The dispute echoes the 1982 war in which the UK defeated Argentine forces that had claimed the region, a conflict that claimed 255 British and 649 Argentine lives. The islands’ residents voted overwhelmingly in 2013 to remain a British overseas territory, a vote that is a key point of contention for both sides. Against this backdrop, the possibility of oil extraction runs risk of reigniting deep‑seated diplomatic tensions that could spill into international courts.
