The article deals with the evolution of the regional policy in the UK whose traditions in this respect are the richest among West European countries. Its genesis is linked with attempts to reduce unemployment in industrialised regions. It is commonly agreed that state interventionism in regional development began with the publication of the Special Areas Development and Improvement Act of 1934 which covered Wales, Scotland, Northern Ireland, and northern England. The article focuses on the assumptions behind the regional policy, its objectives, scope, instruments used, and institutions responsible for its implementation indicating changes made by subsequent Conservative and Labour governments. While the former restricted the scope and volume of support in aid of assisted areas, the latter did the opposite. The regional policy defined and modified by the European Community plays a significant role in determining its shape as much as deregulation, reinforcement of the regional tier itself, predominance of social matters over economic ones as well affective and selective nature of support.
