Each year, the International Political Science Association’s Research Committee on the Structure of Governance sponsors the Levine Prize. It is named in honour of Charles H. Levine, who was a distinguished member of the Research Committee and served on the editorial board of its official journal, Governance. The prize is awarded on the recommendation of a distinguished committee for the best book on comparative administration or public policy published in the previous year. This year’s committee was composed of Professors Jale Tosun (University of Heidelberg, Germany), Caner Bakir (Koç University, Turkey) and Robert Cox (University of South Carolina, United States). The Award Committee has selected Advising Governments in the Westminster Tradition: Policy Advisory Systems in Australia, Britain, Canada and New Zealand, by Jonathan Craft and John Halligan, as the 2021 recipient of the Levine Award. This impressive book advances our knowledge on varieties of policy advisory systems in Westminister type governments.
