The Scottish Labour Party is at an unprecedented crossroads. Though it had been the leading party in Scotland for fifty years, it has now lost the election and office to the SNP. This book addresses, examines, and analyzes the last thirty years of Scottish Labour, from the arrival of Thatcherism in 1979 to the aftermath of the party's defeat in the 2007 Scottish Parliament elections. It asks fundamental questions about the nature of Scottish Labour, its dominance of Scottish politics, the wider politics of Scotland, and whether its decline is irreversible. Surveying both contemporary events and recent history, the volume draws on extensive research in archival sources and interviews significant members of Scottish Labour.
