This book examines the role of the Leader of the Opposition, the Shadow Cabinet, and Opposition Spokesmen in British politics. The prime concern is with the years 1951-70, spanning the 1952-64 period of Labour Opposition, and the 1964-170 period of Conservative Opposition, but to give a fuller perspective references is also made to the historical background to modern practices, and to developments in the post-1970 period of Labour Opposition. Throughout, emphasis is placed on comparing the two parties in terms of their front-bench organization and behavior when in opposition, and in comparing the practices of opposition with those of office.
