Video: Margaret Thatcher's Falklands testimony 'like a film script' Files released by the National Archives at Kew, south-west London, under the 30-year rule reveal the former Prime Minister's hitherto unpublished testimony to the Franks Inquiry into the Falklands conflict. In it, she described her horror when, at the end of March 1982, she became aware that the Argentinians were about to invade. I never, never expected the Argentines to invade the Falklands head-on. It was such a stupid thing to do, as events happened, such a stupid thing even to contemplate doing. Peter Hennessy, Professor of Contemporary British History at Queen Mary University, London, described the transcripts as "vivid." "It is like a film script, it is so vivid it leaps of the page and bites you," he said.
