DAVID Cameron will today mark the 30th anniversary of the invasion of the Falklands with a reaffirmation of Britain's determination to uphold the islanders' right to determine their own future.

Three decades after Argentinian troops seized the islands' capital, Port Stanley, Mr Cameron will pay tribute to the forces sent by Margaret Thatcher to take them back.

The Prime Minister has said it should be a day to remember the 649 Argentinians who died in the conflict as well as the 255 Britons.

The run-up to the anniversary has been marked by a ratcheting-up in tensions between London and Buenos Aires, with the Argentine Government of President Cristina Fernandez de Kirchner reasserting its claim to the islands.

Mr Cameron will say: "Britain remains staunchly committed to upholding the right of the Falkland Islanders, and of the Falkland Islanders alone, to determine their own future."

It comes as veteran and entrepreneur Tony Banks, from Dundee, will today unveil a scheme to help build friendships between the children of servicemen who fought on opposite sides in the conflict.

Mr Banks, from Dundee, was inspired to set up the initiative after tracking down an Argentine soldier whose trumpet had ended up in his possession. The project will link up youngsters in Britain and Argentina via webcams.
