International audience ; This paper examines 'auxiliary' police in three European countries and the extent to which they continue to present a pluralisation of public sector policing. Examining findings from existing empirical research, we will argue that despite different origins, systems of governance, formal powers and levels of centralisation, the police auxiliaries in England, France and The Netherlands have all experienced an overall trend towards becoming more 'enforcement-orientated'. This unique comparative analysis measures each agency's powers, appearance, organisational dimensions and mandate and the associated drivers towards change, such as the politicisation of law and order, large-scale institutional transformations and professionalisation attempts. This analysis will have implications for pluralised policing scholarship as it questions the extent to which auxiliary officers provide a true alternative to the standard or national public policing mandate, which has historically highlighted the 'law and order' function of the police. It also highlights the lack of research on what 'policing by government' (Loader 2000) looks like in practice and the need for further comparative research with these auxiliary state policing actors.
