The United Kingdom, already beleaguered in the mid-1970's by a number of serious problems—economic, social, political, diplomatic and even climatic—in addition has had to contend with a far-reaching constitutional crisis. Involving the subject of devolution of power (better known as home rule), it has been described as “the most crucial constitutional issue which has confronted the United Kingdom since it came into being.” The controversy over devolution has reached a new level of intensity since November, 1975, when the government, in an effort to resolve the dispute, published a White Paper entitled Our Changing Democracy: Devolution to Scotland and Wales. This article examines the following aspects of the devolution issue: its background, why it has emerged at this time, why the White Paper was issued, reasons for the hostile reaction to the White Paper, the prospects for parliamentary passage of devolution legislation, and the issue's political repercussions and implications, both domestic and international.
