Britain has reaffirmed its sovereignty over the Falkland Islands after US President Donald Trump said Washington was reviewing its position on the disputed South Atlantic territory, raising fresh questions over the future of a long-running UK-Argentina dispute.
Trump made the comments on 31 August 2026, saying he reviews every policy position when asked about the Falklands. He did not say whether the review would result in a change to the United States' position.
The development comes after growing pressure on Britain over defence spending and could put another strain on relations between Washington and London.
The British Government has maintained that its position on the Falkland Islands is unchanged.
The UK regards the islands as a British Overseas Territory and has repeatedly said sovereignty rests with Britain while recognising the right of Falkland Islanders to determine their own political future.
The Foreign, Commonwealth and Development Office states that the UK does not doubt its sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands and their surrounding maritime areas. It also says the wishes of the islanders must remain central to any discussion about their future.
That position is backed by the islands' own government, which describes the Falklands as internally self-governing while Britain remains responsible for defence and foreign affairs.
The question of self-determination is central to Britain's response.
In a referendum held in March 2013, 99.8% of voters chose to remain a British Overseas Territory. The vote had international observers and was presented by the Falkland Islands Government as a clear expression of the population's political wishes.
The British Government has repeatedly cited that result when rejecting calls for negotiations over sovereignty with Argentina.
Lord Collins, speaking for the UK at the Organisation of American States in June 2026, said the islanders' right to determine their political future was fundamental and that there could be no change to their status without their consent.
For Britain, Trump's review therefore creates a diplomatic concern rather than an immediate change to the islands' legal status.
Argentina has maintained its claim to sovereignty over the Falklands, which it calls the Malvinas.
The dispute led to war in 1982, when Argentine forces invaded the islands. British forces subsequently retook the territory, with the conflict ending after Argentina's surrender in June that year.
The issue has remained politically sensitive in both countries despite the absence of further military conflict.
