This book bestows academic light in place of disputed ideological heat emanating primarily from Conservative political polemicists on the role, influence and ideological trajectory of the One Nation Group of Conservative MPs. It contributes to the debates on policy and the role of 'think tanks' in such policy formulation over the period 1950-2005; the debate over the existence and extent of 'consensus' in post-war British politics; and to research on political parties in general and factions and tendencies in particular.
