This book has examined four main ideas. The first was the extent to which Heath’s European policy was impacted by the crises of 1973. Second, the continuities between the European policies of Heath and Wilson were explored. Third, Wilson’s motivations for proposing the renegotiation and the nature of the outcome were considered. The final section asked why the public voted ‘yes’ in 1975 and attempted to offer greater context to the outcome of the referendum. The notions of decline and crisis were central themes which help to explain the course of Britain’s diplomacy, the domestic presentation of Community membership and the shape of public opinion in this period. The conclusion reflects on these lines of analysis.
