Argentina escalates legal and sanctions pressure on UK over Falklands oil project

Argentina has imposed new sanctions, obtained an injunction, and initiated arbitration against the UK over the Sea Lion oil development in the Falklands/Malvinas, prompting contractor departures and a further share price decline for Rockhopper. The move escalates a long-standing sovereignty dispute into direct economic and legal pressure on British commercial interests. The effectiveness of Argentina's measures remains uncertain, but the departure of contractors signals tangible operational impact.
