IN this volume Mr. and Mrs. Webb set themselves to build “an efficiently working, genuinely democratic constitution” out of the materials that are already to hand. The distinctive feature of the Socialist Commonwealth of Great Britain will be the division of the labours of our present overworked Parliament between two co-equal bodies, the Social and the Political Parliaments, both elected on a geographical basis by all the adult citizens. The Political Parliament will deal mainly with defence, justice, and foreign-affairs, and will have a keen eye to the protection of the liberty of the individual. To the Social Parliament all else falls—labour, health, education, the control of industry, and care for the interests of generations yet unborn. In the hands of the Social Parliament rests also the power of the purse; from which it may be anticipated that the Political Parliament, for all its nominal equality, will have to mind its “p's and q's.” A Constitution for the Socialist Commonwealth of Great Britain.
