This is the first of a major two-volume work which provides an authoritative account of devolution in the UK since the initial settlement under New Labour in 1997. This first volume meets the need for a comprehensive, UK-wide analysis of the formative years of devolution from the years 1997 to 2007, offering a rigorous and theoretically innovative re-examination of the period that traces territorial politics from initial settlements in Scotland and Wales and the Good Friday agreement in Northern Ireland to early maturity. Bradbury reviews the trajectory and influencing factors of devolution and its subsequent impacts, using a novel framework to set a significant new agenda for thinking and research on devolution.
