Argentina's foreign ministry is weighing a formal protest after the Royal Navy patrol vessel HMS Medway sailed from the Falkland Islands (the South Atlantic archipelago at the centre of a long-running sovereignty dispute between Argentina and the United Kingdom) to the Chilean port of Punta Arenas in early July, with Buenos Aires and London offering contradictory accounts of whether advance notice was given. Argentine officials say the ship passed through waters under national jurisdiction off Santa Cruz province without prior notification, while the British embassy insists it informed Argentine defence and foreign ministry counterparts before the vessel departed on what it described as a logistics and resupply mission. Any Argentine claim is likely to invoke the Madrid II Agreement (a 1990 bilateral accord restoring diplomatic relations and establishing a mutual notification system for military movements in the South Atlantic following the 1982 Falklands War), with Argentina's Secretariat for Malvinas, Antarctica and the South Atlantic still assessing its next steps.
