The Guardian, 2 Jan 2013, Luke Harding and Uki Goni "Thirty years after Britain and Argentina went to war over the Falklands, Argentina's populist president, Cristina Fernández de Kirchner, has returned to the fray with a blistering attack on British 'colonialism' and a demand to hand back 'Las Malvinas'. In a stinging letter to David Cameron, Fernández urges the UK to abide by a 1960 United Nations resolution urging member states to 'end colonialism in all its forms and manifestations'. ... Her letter is published as an advert (pdf) in Thursday's Guardian and other newspapers. ... The advert in Thursday's Guardian seems to have been prepared in absolute secrecy to ensure maximum impact. A source at Fernández's press office said that even they had been kept in the dark about it."

The Sun, 4 Jan 2013, Alex West, Neil Syson & Graeme Wilson: "We have published our own letter in a Buenos Aires paper to warn her: Hands off our territory. ... We fired off our newspaper message to Kirchner in her native Spanish. She accused Britain of stealing the islands in adverts placed in left-wing British papers The Guardian and Independent. But in an open letter today in the Buenos Aires Herald ... The Sun tells her Britain has had sovereignty there before Argentina even existed."

Metro, 4 Jan 2013, Mark Molloy: "Argentines have reacted angrily by burning adverts and British flags after the Sun newspaper took out a full page advert in an Argentinian newspaper warning president Cristina Fernandez de Kirchner to keep her ‘hands off’ the Falkland Islands."

Politics.co.uk, 4 Jan 2013, Ian Dunt: "British newspapers entered into a strange proxy war over the Falklands Islands today, after the Sun published an advert in Argentina's Buenos Aires Herald addressing the territorial dispute. ... While the Guardian was widely criticised yesterday for allowing the ad space to be sold, the Sun also won few plaudits for its move."
