This book focuses on the relationships between public authorities and established/disestablished denominations in the United Kingdom. It is composed of six chapters which look at the situation in England, Wales, Scotland and Northern Ireland, as well as a general chapter on the British constitutional framework. In the introductory part, an explanation of the British legislature, executive and judiciary is presented. The author deals thoroughly with establishment in England and introduces a distinction between high and low establishment. Furthermore, he carries out an analysis of the State legislation which refers to the Church of England and concentrates on the links between the Crown and the Anglican hierarchy; the role of the General Synod; the position of chaplains in hospitals, prisons and armed forces; the role of Archbishops and bishops of the Church of England in the House of Lords; their appointment by the Crown on the advice of the Prime Minister and the duties of parish priests towards their parishioners. This model is studied in the light of the most recent developments and also includes an interdisciplinary analysis about a hypothetical disestablishment for the Church of England. With regard to Scotland, the author looks at the links between the State (especially the Crown) and the Presbyterian Church whilst stressing its almost independent nature. Disestablishment in Wales and the vestiges of establishment which can be found in this model are also explained. In this context, an analysis of the concept of national Church –as a related, but as a different category from established denominations- takes place. Finally, the very controversial Northern Irish religious reality is examined and bearing in mind that the jurisdiction of the Church of Ireland goes beyond Ulster, some references to the Republic of Ireland are included.
