This work investigates the complex and often contradictory relationship between the British Conservative Party and the process of European integration from the end of the Second World War to the early 21st century. N. J. Crowson, a historian specializing in British political history, utilizes archival records and party documentation to trace the evolution of Conservative policy toward the European Economic Community and its successors. The book argues that the party's internal divisions regarding sovereignty and economic alignment have consistently hindered the development of a unified European strategy. By examining key leadership eras, the text provides a framework for understanding how domestic political pressures shaped Britain's external diplomatic posture.

Scholars and political analysts frequently cite this text as a comprehensive resource for understanding the historical roots of British Euro-skepticism. The prose is noted for its academic rigor and detailed documentation of internal party dynamics.
