From 1966 until 1968, the UK confidentially discussed with Argentina the transfer of the Falklands, assuming its judgement would be accepted by the islanders.[55] An agreement on trade ties between the archipelago and the mainland was reached in 1971 and, consequently, Argentina built a temporary airfield at Stanley in 1972.[45] Nonetheless, Falklander dissent, as expressed by their strong lobby in the UK Parliament, and tensions between the UK and Argentina effectively limited sovereignty negotiations until 1977.
