In view of provision for pensions, unemployment benefits and health insurance, the influence of the Poor Law had been greatly reduced since the time of the Liberal Government. The 1929 Local Government Act abolished the Boards of Guardians, and put public hospitals, out-relief and the operation of the Poor Law under the management of local authority committees. The workhouses were renamed as Public Assistance institutions. Local authorities could in principle have stopped implementing some of the Poor Laws at this point. From 1919 to 1925 the Guardians at Poplar in London had refused to levy the high rates needed to pay for their extensive out-relief, and of the 1929 Local Government Act permitted local authorities, subject to ministerial approval, to introduce alternative schemes of poor relief; but the exemption was little used.
