Britain's Entry into the European Community: report on the Negotiations of 1970 - 1972 by Sir Con O'Neill

Soon after the signing in January 1972 of Britain's Treaty of Acccession to the European Community, Sir Con O'Neill, a key figure in the events leading to its successful conclusion, was commissioned by the Foreign and Commonwealth Office to write an internal history of the preceding negotiations. His account provides a detailed analysis of negotiations which had an impact on Britain's relations with its European neighbours, and insights into the processes of multilateral diplomacy.
