'Peter Cane and Harshan Kumarasingham have gathered together an outstanding group of authors, and they have produced a work of the highest quality … the present work is genuinely a constitutional history of the entire United Kingdom and its constituent parts … Unlike previous constitutional histories … this work is jointly authored by historians, lawyers and political scientists. This is of enormous value in making sense of our constitution, as it is based not only on legal documents, or on political understandings and practices, but on a combination of law, politics and practice which encompasses more than one academic discipline.' The Right Honourable The Lord Reed of Allermuir, President of the Supreme Court of the United Kingdom
