Realignment of the Left? [PDF ebook] 
A History of the Relationship between the Liberal Democrat and Labour Parties

This book is concerned with the realignment of progressive political forces in Britain. It focuses on the relationship between the Liberal and then Liberal Democrats and the Labour parties, and seeks to provide an understanding of the factors which have created the potential for the realignment of the centre left of the political spectrum and the forces which have historically impeded its attainment. This authoritative account of the British left and centre since the nineteenth century offers essential background for current politics.
