I am the co-author (with Professor Robert Thomas of the University of Manchester) of 
Public Law, a textbook aimed at undergraduate students studying modules in Public Law, Constitutional Law and Administrative Law. The second edition was published in April 2014, three years after the publication of the first edition. 

Public Law is an advanced textbook that comprehensively covers the key topics found on undergraduate public law courses. The book presents a sophisticated and accessible analysis of the law and institutions of public law, and places the legal issues within the wider socio-political context within which the constitution operates. Three key themes that permeate the content allow students to approach the subject in a structured and easy to understand way, and questions posed throughout the chapters give students the opportunity to provide answers that show how their knowledge has increased as the chapter progresses. The key themes are: (i) the significance of executive power in the contemporary constitution and the challenge of ensuring that those who wield it are held to account; (ii) the shift in recent times from a political to a more legal constitution and the implications of this change; and (iii) the increasingly 'multi-layered' character of the British constitution.

Public Law is accompnanied by an Online Resource Centre which contains updates on recent developments, together with a collection of useful weblinks. There are also additional resources which lecturers can make available to their students, including digital versions of the diagrams used in the book and a bank of self-test questions. The first chapter of the book can be read free of charge, also via the publisher's website. 

The book has been praised by Dawn Oliver, Emeritus Professor of Constitutional Law, University College London: "Lucid and elegantly written, with an admirable lack of jargon. Lively case studies and the insightful identification of key themes bring the subject to life. An excellent, concise but comprehensive textbook for students."
