Argentina's Javier Milei rules out invading the Falklands but vows to get the islands back by diplomacy

Speaking in Madrid on Wednesday, Milei said Britain's 'geopolitical and demographic' problems pose a risk to the region. He repeated three times that his government does 'not believe in military solutions'. He also renewed his threat to block firms drilling for Falklands oil from doing business in Argentina. A tribunal in Hamburg will hear Argentina's bid to halt the Sea Lion oil project on November 10 and 11.

Trump has said he would not back Britain if Argentina invaded: 'Your country was not there to help me.'

Prime Minister Andy Burnham told the UN that Britain 'will stand firm in the face of any threats.'

In a 2013 referendum, 99.8 per cent of Falkland Islanders voted to remain British.
