A Foreign and Commonwealth Office spokesman has issued a firm rebuttal of Argentinian claims that military exercises on the Falklands amount to "provocation".
Argentine claims that we are 'militarising' the South Atlantic are wholly false. UK forces numbers have declined to the minimum necessary to defend the Islands.
Argentina's suggestion that the UK is seeking to threaten militarily either Argentina itself or the wider region is entirely without foundation, as is the suggestion that we deploy nuclear weapons in the region.
These are routine exercises in the Falkland Islands that have happened approximately twice a year for many years
Deputy foreign minister Eduardo Zuain has summoned the British Ambassador in Buenos Aires in a protest over a planned military exercise on the Falkland Islands next week.
A spokesman for the Embassy of Argentina in London said: "The Government of the United Kingdom will conduct military exercises on occupied Argentine territory between 14 and 27 April, including missile launchings from the Malvinas Islands.
"This action falls within a pattern already denounced by President Cristina Fernandez de Kirchner on 2 April, consisting of provocations and hostile acts towards Argentina from an extra-continental nuclear power."
Argentina's president has taken her country's claim to the Falkland Islands to the United Nations, challenging Britain to "act more intelligently" and sit down to talk about the future of the Islands.
In a highly emotional speech President Cristina Fernandez de Kirchner chose to appear at the little-known UN Decolonisation Committee on the 30th anniversary of Britain's ousting of an Argentinian invasion force from the Falklands.
The president used the occasion to reiterate Argentina's opposition to any more wars and to criticise the prime minister's decision to mark the day by flying the Falklands flag over his official 10 Downing Street residence.
Speaking about the hundreds of deaths in the 74-day conflict over the islands, she said: "I felt shame from far away for them because wars are not to be celebrated or commemorated."
Thirty years to the day after the Falklands war ended, the Argentine President will be ramping up the rhetoric over her country's claim to the islands at the United Nations. Cristina Kirchner's speech will be symbolic, coming on the anniversary of the day hostilities ended.

A group of Falkland Islanders have travelled to the United Nations building in New York to hear President Cristina Fernández de Kirchner argue that the islands should belong to Argentina.
Two members of the islands' Legislative Assembly are hoping to address the UN's decolonisation committee to say they want Argentina to leave them alone. Islander Mike Summer said the committee should put the wishes of the people who live there before the interests of anyone else:
"Their responsibility is not to the United Kingdom or to Argentina. It is to the people of the self-governing British territory."
