My right hon. Friend is aware of the circumstances indicated in the first part of the question. Subsidy is being paid on the houses in question. With regard to the last part of the question, Section 10 of the Housing (Financial Provisions) Act, 1024, provides that, in approving proposals for the construction of houses, the Minister of Health shall not impose any conditions which would prevent the materials required being purchased in the cheapest market at borne or abroad. The Government have, however, urged local authorities to arrange that all contracts for or incidental to works carried out by them should, in the absence of special circumstances, be placed in this country. My right hon. Friend understands that in the present case the course adopted has resulted in a substantial saving of cost.
