Does this new collective volume, by a mixed bunch of academics and insiders, have anything to add? Not much, must be the honest answer. Morgan’s biography was a solid study, based firmly on the archives. The Cabinet papers for the period have now been freely available for 20 years. Yet the essays on policy in James Callaghan: An Underrated Prime Minister? offer just a few uninteresting scraps from them, and rely mainly on published works by well-known authorities, such as Donoughue and the historian Peter Hennessy. They add little new.
