The College of Policing coordinates recruitment, training, and the production of ‘guidance’ for the police forces of England and Wales. In the case of Miller versus College of Policing, it was explicitly censured by the High Court, and the undemocratic implications of its illegal guidance condemned. This article investigates how this failure happened, what role interest groups have played, and how the College’s administrative architecture is implicated. By contextualising the College into broader changes in political economy, the article asks whether the rise of a new ‘corporatism’ in British society forms part of the explanation for the College’s failures.
