The last twenty-five to thirty years have been very rich in significant constitutional transformations in the United Kingdom, in the fields of form of State, form of government, human rights and so on. This paper aims to examine the trajectory taken by comparative studies on the UK during this time. The aim is to understand whether, and to what extent, the attention paid by Italian doctrine, and in particular by the Journals Diritto Pubblico Comparato ed Europeo, has been assiduous and fruitful in the examination and interpretation of constitutional events.
