Slum Clearance (Derbyshire) 80. Mr. Scott-Hopkins asked the Secretary of State for the Environment what is the allocation of money for 1972 to Derbyshire for slum clearance; and how this compares with 1971. Mr. Channon No limit is imposed by the Government on expenditure by individual housing authorities on slum clearance. While borrowing for this purpose in 1971–72 has been subject to a block allocation arrangement, this control, as already announced, will be removed from 1st April, 1972.
