According to GB News, Milei gave Britain a two-week deadline to halt any drilling or face legal action, and said he had instructed government lawyers to begin proceedings under the UN Convention on the Law of the Sea.

The Sea Lion project is being developed by Navitas Petroleum, which GB News described as an Israeli firm, with Britain's Rockhopper Exploration as a minority partner. Both developers say they hold valid British-issued exploration licences, according to France 24.

Argentina has long claimed sovereignty over the Falkland Islands, which are administered by Britain. France 24 noted the 1982 war over the territory killed 255 British and 649 Argentine troops.

According to GB News, Milei called the oil venture 'illegitimate' and accused Britain of 'plundering our resources,' and had drawn a comparison to the Labour government's handling of the Chagos Islands.
