Falkland Islands: Argentina Ambassador Says Self-Determination 'Does Not Apply' To Territory

The UK has been deploying "weapons of mass destruction" in the South Atlantic and has no right to the "colonial enclave" of the Falklands, according to Argentina's ambassador to London.

Speaking at a discussion on Anglo-Argentine relations hosted by the London School of Economics on Thursday evening, Alicia Castro said "the principle of self-determination does not apply to the special and particular colonial case" of the Falklands.

"Our government is well-known for policies of human rights. Argentina supports in general the principle of self-determination as established by the UN charter but not every human community is considered to possess this right [of self-determination]," she said.

She told her audience that Argentina was "very unhappy to have a colonial enclave in the south of our continent". The dispute between the UK and Argentina over the sovereignty of those islands, she said, was a "clash of principles".

The ambassador issued a warning on the UK's alleged deployment of a nuclear submarine in the region, describing it as tantamount to using "weapons of mass destruction".

"What is happening today is a growing British military presence in a disputed area, which includes the deployment of a nuclear submarine", she said, adding: "International nuclear weapons in the South Atlantic, as you know, are contrary to the [nuclear non-proliferation treaty] which we support...it amounts to weapons of mass destruction - but we are a land of peace".

Her remarks caused outrage among some in attendance, with suggestions that she should be "expelled" from the country. The ambassador and her team were upset as protesters distributed leaflets at the talk highlighting Argentina's $16bn debt.

This comes after the ambassador tried to ambush foreign secretary William Hague at a public meeting. She urged him to "give peace a chance" by opening talks on the Falkland Islands.

"Seeing that the United Nations and the international community and a large group of Nobel prize winners urge both countries to (start) negotiations in order to find a pacific and permanent resolution, my question is are you ready for dialogue, are we going to give peace a chance?" she asked as Hague took questions from the audience.

Britain maintains that the Falklands are self-governing and that Argentina must talk to the islanders about such matters.
