Milei restates Falklands claim and threatens oil sanctions as UK vows to uphold sovereignty

Argentina's President Javier Milei delivered a prime-time televised address in which he restated his country's long-standing claim to the Falkland Islands, which Argentina calls Las Malvinas, and announced plans to sanction oil companies preparing to drill in the surrounding waters. He said the islands were Argentine "by history and by law" and that securing the territory was "a matter of survival". He singled out the Sea Lion oil field, an estimated 1.7 billion barrels, which is due to be exploited by two companies, Rockhopper Exploration and Navitas Petroleum. Milei said he would introduce a sanctions bill against the firms and anyone working with them, arguing that any new advance on the islands would be considered a threat to national security.

The address came days after US President Donald Trump suggested he was reviewing America's traditional neutral position on the Falklands and hinted that the US might not come to Britain's aid in a future conflict. In an interview with GB News, Trump linked his stance to the UK's failure to support US military action against Iran, saying: "Don't forget, you get a big percentage of your oil from the Strait of Hormuz, and you weren't there to help me." Milei, a close ally of Trump, said the winds of change were blowing in Argentina's favour.

The UK government responded swiftly. Prime Minister Andy Burnham said the Falklands are British and will remain so because the islanders wish it. The Defence Secretary, Wes Streeting, described Britain's commitment as "absolute and unshakable". The Foreign Secretary, Ed Miliband, said the right of the islanders to self-determination is "paramount" and grounded in international law. A Downing Street spokesperson noted the 2013 referendum in which 1,517 islanders voted to remain British, with only three against.

Falkland Islanders themselves played down the significance of the speech. Catherine Daniels, deputy editor of Penguin News in Stanley, said there was "nothing groundbreaking" and that islanders are used to such "background noise" from Argentina. She pointed out that the last minefield was cleared only six years ago and that younger generations remain strongly committed to the British connection.

Military analysts noted that the situation is very different from 1982, when Argentina invaded and Britain sent a task force to retake the islands. There is now a garrison of around 1,500 personnel, four Typhoon fighter jets, air defences and a permanent military base at Mount Pleasant. Simon Weston, a veteran of the 1982 war, said the Argentine navy is "still where we left it, at the bottom of the sea" and that the threat is mostly rhetorical.

The row comes amid a wider UK defence spending crisis. John Healey, who resigned as Defence Secretary over the failure to commit to spending 3% of GDP on defence by 2030, has since become Chancellor and is under pressure to set a clear timeline. The Conservative leader, Kemi Badenoch, said Argentina's threat was an indictment of the Labour government's "weakness" and cited the decision to surrender the Chagos Islands as a signal to opportunists. However, the government insists it remains committed to reaching 3.5% of GDP by 2035.
