This book examines Conservative backbench debate on European integration and British relations in the Middle East between 1948 and 1957. In seeking to compare the impact of a loose affiliation of Conservative MPs, an organized faction of longstanding and an ad-hoc pressure group, the text concentrates upon the Europeanists, the Suez Group and the Anti-Suez Group and considers their attempts to influence British foreign policy, using interviews with former parliamentarians and contemporary sources, published and unpublished.
