of a local authority." In 1951, a comforts allowance was introduced that was automatically paid to war pensioners "receiving unemployability supplement and constant attendance allowance." A more extensive system of social welfare benefits was established by the Attlee Government, which did much to reduce acute social deprivation. The cumulative impact of the Attlee's Government's health and welfare policies was such that all the indices of health (such as statistics of school medical or dental officers, or of medical officers of health) showed signs of improvement, with continual improvements in survival rates for infants and increased life expectancy for the elderly. The success of the Attlee Government's welfare legislation in reducing poverty was such that, in the general election of 1950, according to one study, "Labour propaganda could make much of the claim that social security had eradicated the most abject destitution of the 1930s". Housing The New Towns Act of 1946 set up development corporations to construct new towns, while the Town and Country Planning Act of 1947 instructed county councils to prepare development plans and also provided compulsory purchase powers. The Attlee Government also extended the powers of local authorities to requisition houses and parts of houses, and made the acquisition of land less difficult than before. The Housing (Scotland) Act of 1949 provided grants of 75% (87.5% in the Highlands and Islands) towards modernisation costs payable by the Treasury to local authorities. In 1949, local authorities were empowered to provide people suffering from poor health with public housing at subsidised rents. To assist home ownership, the limit on the amount of money that people could borrow from their local authority in order to purchase or build a home was raised from £800 to £1,500 in 1945, and to £5,000 in 1949. Under the National Assistance Act of 1948, local authorities had a duty "to provide emergency temporary accommodation for families which become homeless through no fault of their own." A large house-building programme was carried out with the intention of providing millions of people with high-quality homes. A housing bill passed in 1946 increased Treasury subsidies for the construction of local authority housing in England and Wales. Four out of five houses constructed under Labour were council properties built to more generous specifications than before the Second World War, and subsidies kept down council rents. Altogether, these policies provided public-sector housing with its biggest ever boost up until
