Argentina lodges legal claim against UK's Falklands oil exploration

What the report says

Argentina has begun legal action at the International Tribunal for the Law of the Sea in a bid to halt oil and gas exploration north of the Falkland Islands, deepening a long-running dispute with the UK over the South Atlantic territory. According to BBC World News, Buenos Aires argues that the exploration was authorised unlawfully by Britain and says it is seeking to protect its sovereign rights over the area and its continental shelf.

The move follows recent pressure from President Javier Milei, who has called for the Sea Lion oil project to be scrapped and previously threatened sanctions against firms involved in activity near the islands. The field, operated by Britain’s Rockhopper Exploration and Israel’s Navitas Petroleum, is expected to begin production in 2028 if development proceeds. The Falkland Islands government has extended exploration licences, while the UK says the activity is lawful and regulated by the islands’ administration.

UK ministers rejected Argentina’s claims and said they would defend businesses working in the Falklands. Foreign Office minister Uma Kumaran described Argentina’s campaign as economic coercion, while Foreign Secretary Ed Miliband said companies should be able to make lawful commercial decisions without political pressure. The dispute comes against the backdrop of the 1982 war and Argentina’s continuing claim to the islands, known there as Las Malvinas.
