Writing with the advantage of post-war perspective, Jenkins gives an insightful account of the battles surrounding the Parliament Act and the move towards the supremacy of the House of Commons. The work has aged well over the decades, with Jenkin's analysis as fresh as when he wrote it. Indeed, a mid-20th century perspective, particular from one of Jenkin's intellectual stature, is helpful - far enough from the events themselves to be impartial, without being caught up in the latest changes and machinations with regard to the upper house.
Jenkins sets out the stragies and motivations of the different sides clearly, and in as impartial a manner as can be expected (given that a modern perspective is highly unlikely to sympathise with those peers seeking to preserve the status quo). There is little "demonising" of the conservative factions, and the book is an informed and intelligent insight into a critical turning point for the British constitution.
