After surveying the various forms of devolution, attention is drawn to the arrangements for the devolution of certain powers to local authorities in particular areas of England. These can be grouped into three spatial levels: the metropolitan county; the non-metropolitan county; and the region. Although the devolved powers (in terms of particular functions or services) are similar, their depth and complexity varies across spatial levels. The major historical and political characteristics of each spatial level are discussed, together with the associated benefits and limitations of devolution. The conditions under which devolution to different levels may take place are then examined. The overall effect of the programme in England will inevitably cause the devolution landscape of the UK to assume an increasingly uneven structure. KEYWORDS legislative and administrative devolution, metropolitan county, nonmetropolitan county, region 1 | INTRODUCTIONThe transfer of political power from one level of government to a lower level (sometimes referred to more generally as "decentralization") has been undertaken in a number of nations over recent decades. These include France, Italy and Spain, where regional governments have been in existence for some time. The powers and responsibilities have varied among nations, and have involved such areas as infrastructure investment, spatial planning, public transport and higher education. The discussion to follow is based on a case study of this transfer of powers and responsibilities within a particular nation (the UK), where the process is termed "devolution."
